Special Report: Getting the Optimal Return on X-ray EquipmentCarestream
Radiology administrators need to meticulously analyze their spending to get the best possible return on their investment in medical imaging equipment. In this special report, we explore several approaches to get the maximum return on this important capital investment.
Certainty-based location* accuracy with the capability of segmenting the work space into clinically meaningful zones (or areas). For clinical workflow, zones are typically patient rooms, patient bays, nursing stations, hallway segments, and other areas meaningful to provide care to patients. Mobile zones such as wheelchairs and stretchers are also opportunities to define a patient care area. Accuracy is thus defined as the ability to know with certainty that an asset is in a defined zone. If there is significance to know where the asset is within a zone, then the zone should be divided into smaller zones.

The network helps provide patients in remote communities with better local care by allowing remote radiologist diagnosis and consultation.
The transformation to digital imaging is complete. The transformation to digital records is underway. The addition of networking capability to clinical devices (pumps, patient monitors, nurse call systems) and everyday objects (doors, thermometers, water sensors, signs) grows with each passing month. Your network needs to be ready for the hyper-connected near term.

This document discusses the risks of low-level radiation exposure from medical imaging procedures like CT scans. It notes that while there is no scientific consensus on radiation risks, international organizations assume the linear no-threshold model which states that any increase in radiation dose, no matter how small, results in an incremental increase in risk. The document outlines strategies that radiologists can employ to optimize CT protocols and reduce radiation doses for patients, such as using automatic exposure control, iterative reconstruction techniques, indication-based protocols, and monitoring doses at the patient and department levels. Radiologists are urged to take the lead in minimizing radiation exposures from medical imaging when it is clinically appropriate.

Closed bore MRIs have a small opening of around 60cm, which can cause claustrophobia. They provide excellent image quality due to their high magnet strength between 1.0T and 3.0T. Open MRIs have openings on three to four sides, allowing larger or claustrophobic patients to fit more comfortably, but have lower magnet strengths between 0.35T to 1.2T, resulting in lower image quality. Wide bore MRIs combine the benefits of closed and open bore MRIs, with a larger 70cm opening and magnet strengths providing high quality images in shorter times.

Who needs fast data? - Journal for Clinical Studies KCR
How “no news” during the life of a trial is bad news, and what data management (among other things) can do to help when ensuring access to fast data? Get to know this and more about smart e-solutions in the newest article of Kaia Koppel, Associate Director, Biometrics & Clinical Trial Data Execution Systems at KCR, in the recent issue of Journal for Clinical Studies (p.40-21).
This document describes a radiologist's experiment adding two additional monitors to reading workstations to improve workflow efficiency. The radiologist was able to add two 30-inch, 4 megapixel monitors, a video card, and free software to existing workstations for under $1,000. This doubled the screen real estate without increasing costs. In a trial period, radiologists reported major improvements to ergonomics, ability to compare multiple datasets simultaneously, and opening multiple applications at once. The radiologists estimated this setup could save 30 seconds per case and concluded it was a cost-effective way to improve efficiency without additional spending.

In the past decade, there has been a significant increase in the use of Data Monitoring
Committees (DMC) and Adaptive Designs (AD) in clinical trials. While the monitoring of safety
data by a formal committee is not required for all clinical trials, it has become the norm to have
a formal DMC conduct periodic safety reviews for any controlled trial that evaluates treatments
intended to prolong life or reduce risk of major adverse health outcomes, or for trials that
compare rates of mortality or major morbidity. Confirmatory, pivotal, and adaptive design trials
have more complex operational issues requiring an external and independent DMC. The DMC
may have access to unblinded interim data, be required to make expert recommendations
about how the trial should continue, and then ensure that planned adaptations are
implemented as outlined in the protocol without involving the sponsor or exposing it to
unblinded data or results.
This added complexity creates a challenge and a question: how can the DMC, statisticians, and
sponsor effectively communicate, share blinded and unblinded data, perform analyses, and
implement adaptations without introducing operational bias or compromising the integrity of
the trial? One solution is to utilize a sophisticated computer system that can provide the
security and necessary firewalls to ensure that interim data is only accessible to those it is
intended for, that the rules and processes outlined in the protocol and DMC charter are
enforced, and that communication between the DMC and sponsor is effectively facilitated while
protecting the integrity of the trial and preventing the introduction of operational bias.
The system must also provide an audit trail that tracks “who saw what and when” providing
evidence to regulatory authorities that the protocol was strictly followed with a minimal
possibility of bias. This white paper describes the computer system, ACES, which Cytel has built,
that makes all of this possible. ACES (Access Control Execution System) has been purpose-built
to address the operational complexities inherent in adaptive design and pivotal clinical trials.
ACES is a computer system designed to facilitate communication and data sharing during clinical trials using adaptive designs or those with interim analyses. It provides security to ensure only authorized individuals can access interim data and implements audit trails to track access. ACES automates administrative tasks and stores documents, analyses, and trial records to help regulatory agencies ensure protocols were followed. It was used in a seamless phase 2/3 oncology trial to securely share interim analysis reports with the independent DMC and notify stakeholders of their recommendation while preventing unblinding of the sponsor. ACES aims to build trust in adaptive design trials by transparently demonstrating protocol adherence.

KNN achieved higher accuracy at 95.74% compared to 92.6% for decision tree. The pathology report analyzer extracts text from scanned reports using Tesseract OCR to provide a graphical analysis and easier interpretation of test results. The goal is to provide immediate and accurate disease prediction and medical consultation through a conversational interface.

Who Monitors the Monitors? Automated, Hierarchical Data Quality Assessment fo...Power System Operation
Distributed sensor systems are a critical component required for the operation of a reliable, resilient, and efficient electrical grid. However, just as the grid requires monitoring, so too does the sensor system itself. Therefore, the continuous assessment of the quality of the data captured by sensors becomes an important obligation and task for transmission and distribution system operators. This paper examines the underlying philosophy of data quality assessment and then uses this perspective to craft a set of requirements for an operational system. The paper then discusses one potential system implementation that meets or exceeds the requirements posed and then examines a few ways data quality assessment could evolve.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

An Approach to Automated Techniques for Data Extraction and Integrity Validation of CT Dosimetry Reports
1. An Approach to Automated Techniques for Data Extraction and Integrity Validation of CT Dosimetry Reports Jaron Chong Diagnostic Radiology Resident, PGY-1 Department of Radiology McGill University Health Centre CAR ASM 2011 Educational Exhibit EE137
2. Why Dose? With ever increasing utilization of Computed Tomography (CT) scanners, there is increasing pressure for greater accountability, reporting, and analysis of CT dosimetry. Recent focusing events such as the Cedars Sinai incident in California and the Jacoby Roth incident at an E.R. in California have resulted in vendor recalls, redesigns, and heightened public anxiety and attention regarding radiation dose. General concern about dose has reached public awareness from thyroid shields on the Dr. Oz Show to prime-time TV show reports on the dangers of CTs and the Fukushima nuclear reactor. While most reports are over-sensationalized, our collective ability to control and respond to these issues have been limited by our usage of dose reports.
3. Anatomy of a Dose Report Each Dose Report is a DICOM Screen Capture, a bitmap representation of a dose estimate generated by the scanner. Images are generally stored as lossless images and are quite large in size, occupying approximately 528kB per page of report. These reports are usually labeled #999 or #501 as the series number.
4. Changing Our Mindset At the time, this solution of storing information as a bitmap was geared towards providing an audit trail — metaphorical receipts in shoeboxes. From a technical perspective, the information is all there, but from a practical perspective, we have previously lacked the tools to address some important questions ranging from alerting radiologists to acute overdose events to more subtle issues like the comparison and evaluation of new scanners, protocols and quantifying the radiation dose exposure through the lifetime of a patient. Information is only as good as it is accessible and accessibility has been poor. [Shoebox of Receipts]
5. The Core Principles of Audits Performing and comparing approaches to audits should be guided by core principles that will determine the best approach. Audits should promote structured textual data, to allow for proper analysis. The process should be fast and accurate, and complete with as many records as is possible in these analyses. Finally, audits would be made routine and integrated into day-to-day practice, as much as possible. Of these it is important to emphasize the first two. Structured Data Complete Fast Accurate Routine
6. Structured Data It is only from structured information that we will be able to enable routine real-time alerts of dosimetry and longitudinal analyses of the tens of thousands of scans we perform annually. Only through the creation of textual and analyzable data can we appropriately monitor and improve our protocols in a responsive fashion to our patients. While some attempts to generate structured data have been attempted, such as the development of the Radiation Dose Structured Report, it still remains very difficult to access dosimetry data. Meta-information on scanning parameters and clinical indications is often hidden in the DICOM Headers or other virtual silos of information.
7. Complete Audits No Overdoses No Overdoses* VS In order to guarantee safety we require complete audits. There is a palpable difference between: “In a sample of 100 Head CT’s, none were found to exceed recommended radiation doses.” versus “In our institution, no Head CT’s exceeded recommended radiation doses.” One statement is academic while the other is one you could take to court. In business, you would never audit a company by only looking at 10% of the financial records. Why should radiology be any different?
8. The Problem With Dose Reports Achieving these principles has not been, and will not be easy. As information is locked into an image, it has traditionally been laboriously intensive to perform dosimetry audits. The vast majority of studies examining dose are done prospectively with limited achievable sample sizes in mind. As for retrospective studies, these are usually limited to time spans that can be manually transcribed, and often come months if not years after the scans have been completed. Audits are slow, labour-intensive, complex, and seem out of the way for the typical radiologist.
9. Optical Character Recognition However, starting in 2010, we now have software tools that are capable of performing Optical Character Recognition on dose reports. DoseUtility, made available by Dr. David Clunie and packaged into a server-hosted platform by Dr. Tessa Cook called RADIANCE at RSNA 2010 fundamentally changes the way we can go about performing dose audits. This novel software has been custom-built to be fast, accurate, and customized to solving the crucial step of converting the bitmap Dose Report into text.Using this software, it is now possible to either analyze a set of DICOM Dose Reports manually in very large batches, or to have a dedicated server that can OCR dose reports automatically and convert them into a structured queryable database. We call these two techniques: Semi-Auto OCR and Auto OCR.
11. Comparison of Audit Techniques Comparing audit techniques, it is readily apparent that on all measures, computer-assisted audits represent a significant improvement in terms of speed and breadth of analysis. However, amongst the computer assisted methods, RDSR is vendor specific with no available tools for analysis. Between Auto and Semi-Auto, the difference is fundamentally whether your local IT support exists for implementation of a fully automated server.
12. RDSR: The R’s Aren’t For Ready Radiation Dose Structured Reports without a doubt represent the future of CT dosimetry. Painstakingly formulated over the past decade, RDSRs represent an industry-standardized way of reporting dose that is importable to dose registries. However, there are numerous disadvantages at present: RDSR is not available on all scanners: Only the latest scanners from vendors have enabled the functionality to export these reports. In some cases, this is only scanners installed in the past 2 years. RDSR ignores our archives: All of the information collected from our nearly 10-year old digital archives is ignored. The earliest dose history of patients is ignored. RDSR is a ‘black-box’ with no tools: For those of us lucky enough, RDSR is being archived on our PACS (e.g. Series #997 Dose Record) but as a ‘black-box’ without the tools for analysis. It is possible to export RDSR files from PACS, but there is no incentive for vendors to provide us with tools to analyze these files, let alone RDSR’s made from the hardware of other vendors. For institutions with multiple vendors, achieving interoperability is challenging. Once RDSR becomes the norm, it will revolutionize the way we think about dose reports. But this may only come after 2 or 3 more hardware upgrade cycles which conservatively could be another 5, possibly 10 years away.
13. Can You Do Full Auto? Without a doubt, having a fully automated audit system is at present the optimal solution. The difficulty is with implementation. Fully automated monitoring requires: Setting up a ‘XAMPP’ server, which is an Apache/PHP/MySQL server, analogous to setting up your own webserver. This requires dedicated hardware and support service, something that all institutions may not have or be able to easily obtain. Even if it is technically possible to do so, there are also political hurdles to approve such a monitoring solution on your live clinical PACS network. The RADIANCE group has made tremendous strides in delivering documentation to setting up such a server, but it still requires significant technical expertise.
14. Semi-AutomatedAudit Protocol The Semi-Automated Audit Protocol, which is the method this document will describe, revolves around using the OCR software as a manual tool instead of part of an automated server. In doing so, we avoid the setup of a server, but experience the slight inconvenience of having to run each processing step manually. In practice, the most time-consuming step is the collection of raw DICOM files. Depending on whether you have the assistance of your PACS administrator, and whether your PACS can export Dose Reports in batch, Semi-Auto can offer nearly all of the speed of Auto, while avoiding the technical difficulty of establishing a dedicated server.
15. Semi-AutomatedAudit Protocol If it is possible for you to perform the first step, the remainder of the protocol: subjecting the DICOM Dose Reports to Optical Character Recognition and Extracting Information from the DICOM Headerscan be done on any desktop computer with freely available software. The merging of the two streams of information, can be done with Microsoft Access, part of a standard MS Office Suite. Analysis of the processed table can be done with traditional statistics tools like the commercial IBM SPSS or open-source PSPP. Full web links to the software mentioned are detailed at the end of this presentation.
16. #1: Collect the DICOMs Dose Reports Methodology on how to collect the DICOM files of the Dose Reports will vary depending on your particular PACS. If possible, seek the assistance of your PACS administrator in order to do a bulk export of all relevant Dose Report series. If such support is not possible, most PACS implementations have the ability to export complete DICOMs. Relevant studies can be searched for and exported. If given the option, try to export only the Dose Report and not the actual clinical acquisition to save disk space. For G.E. scanners, dose reports are labeled Series #999, Siemens Series #501, and Phillips Series #1. On our own PACS (IntelleViewer, Montreal, QC) we found that querying in 2-4 day intervals was necessary in order to fall under the maximum results threshold. Studies were exported and saved under corresponding folders labeled “YYYY-MM”.
17. #2: OCR Dose Reports To recognize the Dose Reports, we used DoseUtility, a cross-platform Java application. After starting up the utility, click Import and select the desired month of DICOMs. For settings: uncheck ‘Show tabular layout’ uncheck ‘Process only dose series’ uncheck ‘Show only dose summary’ These settings are necessary to generate a complete text-only report that contains both the dose summary as well as individual series details. Click Report. Copy, Paste, and Save the Report into Notepad. Repeat as necessary.
18. #3: Extract DICOM Headers OCR is not definitive. There is very useful data only contained within DICOM Headers that needs to be extracted and correlated with the OCR record. Most notable among these are Protocol Names, Additional Patient History, Referring Physicians, and CT Console Names. In order to extract DICOM Header information, we used custom-built scripts made in Python/PyDICOM which are available on our website. These script programs recursively go through the folders and generate monthly tabular reports.
19. #4: Filter / Validate / Remove Duplicates At every juncture, various checks should be performed to ensure images are being correctly recognized, that the case records are valid, and that any duplications are being removed so as to not artificially inflate statistics and frequencies. Relevant to validation is the removal of any external imported studies that are not native to your site. Duplicates can be removed using Excel or SPSS by sorting out the rows of the tables and searching for records with identical variables such as Accession Number and Acquisition Date/Time.
20. #5: Merge 1 4 3 2 Merger of the two data streams is accomplished by (1) importing both filtered tables into MS Access. The two tables in MS Access are joined using a common index (2) usually by using the Accession Number. (3) Finally, a query is made that combines fields from both the OCR table and the DICOM-Header table. (4) The results can then be exported into a Tab-delimited or Excel file for final analysis.
21. #6: Analysis of the Processed Table Analysis is conducted as you would do with any other study. Spreadsheet data can either be manipulated directly in Excel or more powerful statistical analyses can be done with a dedicated statistics program like IBM SPSSor Open-Source PSPP.
22. Tips / Pitfalls ACCESSION NUMBERS ARE NOT UNIQUE: Depending on the practices of your institution, a single accession number may be shared across several different examinations or repeat examinations. Your analyses should take this into account. DUPLICATES ARE INSIDUOUS: As a corollary of the above pitfall, if you use the Accession Number as your unique identifier, duplication is possible, especially after the matching step. Be thorough with your filtering for duplicates and if possible, identify them using SPSS and its duplicate cases function. BEWARE OF DELIMITTERS: There may be numerous inconsistencies in the way technicians enter in Study Descriptions. If certain characters are used such as “quotation marks” or <Tab>, your imports and exports may be damaged. It is worth it to grossly inspect your data in Excel before committing for full analysis. PROTOCOL DIVERSITY:It goes without saying that the generalizations you make will rest upon accurately categorizing and grouping types of protocols. If a protocol manual is available, become familiar with it to learn your institution’s vocabulary and if not, recruit the consultations of your staff to determine which protocols deserve to be grouped together. ONLY SOME VENDORS ARE SUPPORTED: DoseUtility currently supports GE, Siemens, and Phillips dose reports. While active development is still in progress, CT Scans and Dose Reports from other hardware vendors are not guaranteed to work. CHANGE IS A CONSTANT: Be wary while interpreting trends in dosimetry because protocols will vary by site and across time. In addition, subtle changes in settings can result in unexpected findings in your dataset. Full consultation with your site’s physicists and technicians is recommended to draw a better understanding of why doses are the way they are.
23. Post-Processing: Advanced Analysis Beyond the level of this presentation, it is also possible to use the Python programming language and a module, PyDICOM to do much more sophisticated analyses. For example, our institution’s audit is able to take into account overlapping series by reading in the minimum and maximum ranges, and the radiation of each series. These kinds of calculations are quite onerous for manual audits but can be algorithmically determined by computer. All this is made possible through the enabling of structured data.
24. Conclusion Audits can be fast. Audits can be easy. There is no excuse not to do them. We now have the tools to do fast, accurate, and complete audits. If you have access to the IT expertise to implement a fully automated audit system like RADIANCE you can develop a very powerful database for quality control and research purposes. If you do not have access to IT expertise, we have hopefully introduced you to some of the tools to enable significantly more powerful semi-automated audits in this presentation that with a little bit of effort, can allow you to achieve results comparable to fully automated techniques. These techniques have allowed us to do a complete dosimetry audit of a year’s worth of 40,000+ CT’s in 2 weeks…

Editor's Notes
Canadian Association of RadiologyEducational Exhibit AbstractSHORT TITLE:Approach to Extraction of CT Dosimetry ReportsTITLE:An Approach to Automated Techniques for Data Extraction and Integrity Validation of CT Dosimetry ReportsAUTHOR(s):Jaron Chong, JorgyHegyi, Jeffrey ChankowskyINSTITUTIONAL AFFLIATION:Department of Radiology, McGill University, Montreal, QCLearning Objectives:This exhibit reviews the fundamentals of CT radiation dosimetry physics and the implementation of an automated dose report audit system using custom optical-character recognition (OCR) software (e.g. PixelMedDoseUtility; RADIANCE). We examine common pitfalls with automated report extraction. Finally, we review important post-processing approaches to categorization of study groups as well as applications of structured radiation dosimetry data such as hardware audits, protocol evaluation, and multi-site dosimetry audits.Summary:With the increasing utilization of Computed Tomography (CT) and escalating radiation dose being delivered to patients, much attention has been drawn towards the importance of radiation dose audits. Standard of practice at many institutions has dosimetry information being archived in graphical format alongside clinical PACS. This archival is poorly suited for comprehensive and structured queries making audits time and labour intensive.Recent developments in Optical-Character Recognition (OCR) software now allow for the bulk data extraction of dose reports with high accuracy and volume (e.g. PixelMedDoseUtility; RADIANCE). The application of such software to real-world environments presents unique challenges with data extraction and validation of report information. Dose report formats vary between hardware vendors and not every report can be recognized with automated techniques. Site-specific differences in recorded study information can make data analysis difficult. Relevant clinical information may not be present in the dose report requiring cross-referencing between disparate information sources.This educational exhibit will introduce members to current software and approaches to improve their own quality control efforts and review our institution's experiences with addressing the above issues.
