Digital radiography uses digital x-ray sensors instead of film. Images are captured digitally and processed into viewable pictures by computer software. It has advantages over traditional computed radiography like lower radiation dose, ability to enhance images, faster image viewing, and easier sharing. However, it also has disadvantages like higher cost, detectors that cannot be sterilized, and a learning curve to using the new technology. Overall, digital radiography provides benefits for general radiography, dental radiography, and mammography applications.

Radiation protection in nuclear medicine.ppt 2
This document provides guidance on radiation protection procedures for radionuclide therapy, including administration of therapy, management of radioactive patients, and optimization of protection for medical staff, visitors, and the hospitalized patient. Key points addressed include justifying therapy based on clinical benefits, ensuring proper training and responsibilities of medical personnel, constraining doses to comforters and visitors, providing instructions to hospitalized patients, and surveying rooms prior to releasing patients or decommissioning areas.
MAMMOGRAPHY final.pptx
Jacob Gershon Cohen was an early pioneer of mammography in the 1950s and published findings demonstrating its effectiveness for breast cancer screening. Mammography involves using low-dose x-rays to examine breast tissue for abnormalities. Recent advances include digital mammography, which produces electronic images, computer-aided detection to flag suspicious areas, and breast tomosynthesis providing 3D views. Mammography is used both for screening asymptomatic women and diagnostic evaluation of those with breast symptoms, though it has limitations and does not guarantee cancer detection.
Radiation protection
This document discusses the history and development of radiation protection. Some key points:
- The harmful effects of radiation were initially not well understood after X-rays were discovered in the late 19th century. Several early researchers and technicians suffered health effects.
- Over time, concepts like tolerance doses, maximum permissible doses, and the "as low as reasonably achievable" principle were developed to set safe radiation exposure limits.
- International organizations like the ICRP and IAEA were formed to make recommendations on radiation safety standards and regulation. National bodies like AERB regulate radiation protection in India.
- The principles of justification, optimization and dose limitation form the foundation of modern radiation protection practices and regulation. Exposure
Computed Tomography Dose Index
Computed Tomography Dose Index, Includes various CTDI parameters and the way of calculating effective dose from various Computed Tomography procedures along with their conversion factor.
Radiographic film
X-ray film was originally recorded on glass plates but nitrocellulose film replaced them during WWI due to its greater feasibility. Double emulsion film was later found to respond faster to x-rays. By 1924, cellulose acetate replaced the flammable nitrocellulose film. Radiographic film consists of a polyester base and emulsion layers containing gelatin and light-sensitive silver halide crystals. Exposure to x-rays or light from intensifying screens causes a latent image in the crystals that is developed to produce the final image. Factors like contrast, speed, and spectral matching must be considered when selecting a film.
Sensitometry3
This document discusses sensitometry, which is the quantitative evaluation of how a photographic film responds to radiation and processing. Sensitometry involves producing a sensitometric strip by exposing a film to different levels of radiation and then plotting the characteristic curve. The characteristic curve shows the optical density of the film plotted against the log of relative exposure. Key features of the curve include gross fog, threshold, contrast, latitude, speed/sensitivity and maximum density. Understanding a film's sensitometric properties allows for reproducing an invisible x-ray image with optimal contrast and detail.
Radiation protection, its hazards & aerb guidelines
The document discusses the history of radiation protection, including early pioneers who discovered radiation hazards and effects. It describes some key events like the establishment of the ICRP and AERB, and definitions of key radiation terms. It also outlines the biological effects of radiation exposure, distinguishing between deterministic and stochastic effects. The three principles of radiation protection - justification, optimization and dose limitation - are explained.
TLD
This document provides an overview of thermoluminescence dosimeters (TLDs), which are personal radiation monitoring devices. TLDs work by storing radiation energy absorbed from ionizing radiation and releasing it as visible light when heated, allowing the measurement of accumulated radiation dose. The document discusses how TLDs are constructed using lithium fluoride chips, how they are read using a TLD reader, and their use for measuring whole body and extremity doses. The advantages of TLDs include their tissue equivalence, reusable design, and high sensitivity for measuring radiation over time periods of months.

Radiation Protection
The document discusses the history and development of artificial intelligence over the past 70 years. It outlines some of the key milestones in AI research from the early work in the 1950s to modern advances in deep learning. While progress has been made, fully general artificial intelligence that can match or exceed human levels of intelligence remains an ongoing challenge that researchers continue working to achieve.
Digital Radiography
Digital radiography systems have replaced analog film-based systems. There are several types of digital radiography including computed radiography, scanned projection radiography, and indirect and direct digital radiography. Computed radiography uses a photostimulable phosphor plate to capture x-rays and a laser scanner to read the plate digitally. Scanned projection radiography functions similar to a CT scanner to produce digital radiographic images. Indirect and direct digital radiography use detectors like CCDs or photodiodes coupled with scintillators to directly convert x-rays to digital signals. Digital radiography allows for post-processing of images and reduces need for film and processing.

Radiographic exposure and image quality
The document discusses various radiographic exposure factors and how they influence the quantity and quality of x-radiation exposure to patients. It describes how factors like kVp, mA, and exposure time determine the radiation dose and beam quality. It also discusses how the design of the x-ray machine like focal spot size, filtration, and high voltage generation impact technical settings. Film factors like sensitometry, contrast, and processing also influence radiographic image quality.
Radiation units
Radiation units can be divided into units of radioactivity and units of radiation dose. The curie and becquerel are units of radioactivity, with 1 curie equal to 3.7x1010 decays per second. Exposure dose is measured in roentgens or C/kg, while absorbed dose is measured in rads or grays. Equivalent dose accounts for radiation type and takes the Q factor into account, measured in rems or sieverts. Effective dose considers radiation exposure to different tissues, calculated from equivalent dose and tissue weighting factors.
Dose reduction in Conventional Radiography and Fluoroscopy
This document summarizes techniques to reduce radiation dose in diagnostic radiology, including fluoroscopy. It discusses using the smallest x-ray field, increasing distance between the patient and x-ray source, using filters, grids, and intensifying screens. It also covers automatic processing, avoiding unnecessary repeat images, and techniques to reduce dose in fluoroscopy like intermittent exposure, removal of grids, and last image hold. The document emphasizes training operators and using radiation only when necessary to obtain diagnostic information.

Multisection tomography and Transaxial Tomography
1) Multi-section tomography allows for multiple layers or sections of the body to be imaged simultaneously using a single exposure, reducing scan time and radiation dose compared to traditional tomography.
2) Transaxial tomography images sections of the body transversely using a rotating chair and stationary x-ray tube, allowing for coronal and sagittal plane images.
3) Computerized tomography (CT) evolved from early tomography techniques through advances in reconstruction techniques, pioneered by researchers including Radon, Bracewell, Oldendorf, Cormack, and Hounsfield.
ICRP-International commission on Radiation Protection
The International Commission on Radiological Protection (ICRP) is an independent non-governmental organization founded in 1928 to provide protection, recommendations, and guidance on radiation protection. The ICRP aims to contribute to an appropriate level of protection for people and the environment against radiation exposure without unduly limiting desirable human actions. It has developed the International System of Radiological Protection based on scientific understanding and value judgments, applying three fundamental principles: justification, optimization of protection, and dose limits. The ICRP is made up of over 200 volunteers from 30 countries representing leading scientists and policymakers in radiological protection.
Viewing and recording the fluoroscopic image
The document describes the process of viewing and recording intensified fluoroscopic images. It discusses how an image intensifier converts visual light images into electrical signals that are then viewed on a video monitor or recorded. Recording can be done using spot film cameras, cinefluoroscopy movie cameras, or by recording the video signal from the television camera onto magnetic tape, discs, or optical discs. The television camera converts the light image back into an electrical video signal for viewing, storage, or transmission to other viewing locations.
MACRORADIOGRAPHY.pptx
Macroradiography is a radiographic technique used to magnify images relative to the object being imaged. It works by increasing the object-to-film distance, which magnifies the image size. Key factors that affect image quality include geometric unsharpness, which increases with magnification, and limitations of the x-ray tube's fine focal spot, which restricts output. Macroradiography is useful for examining small bony structures and pulmonary patterns at higher magnification.
What is Nuclear Medicine and PET?
Nuclear medicine uses radioactive substances to diagnose and treat disease. In diagnostic nuclear medicine, a radiopharmaceutical is administered to the patient and detected by a gamma camera to produce images of organ function. Positron emission tomography (PET) uses radiopharmaceuticals that emit positrons to produce highly accurate images of metabolic activity in the body, making it effective for cancer diagnosis, staging, assessing treatment response, and detecting recurrence. PET's most common radiopharmaceutical is fluorodeoxyglucose (FDG), which is taken up by metabolically active cells including many cancers.
Filters and beam restrictors
This presentation discusses x-ray filtration and beam restriction. It describes how filters absorb low energy x-rays to harden the beam and reduce patient exposure. Various types of filters are discussed including inherent, added, and compensating filters. Beam restrictors like aperture diaphragms, cones, cylinders, and collimators are also summarized. Collimators provide rectangular fields and allow visualization of the beam's edge and center. Automatic collimators precisely match the beam size to the cassette. In summary, filters and restrictors improve image quality and reduce scatter while limiting exposure to relevant anatomy.
MDCT Principles and Applications- Avinesh Shrestha

How digital x-ray technology enhanced the process of diagnosis.pdf
The x-ray technology has created a huge impact on the medical diagnosis industry. This transformative technology has transcended the constraints of traditional radiography
COMPUTED RADIOGRAPHY
This document discusses computed radiography (CR), which is an indirect digital radiography technique. In CR, x-rays create a latent image on a photostimulable phosphor plate, which is then read with a laser and converted to a digital image. This allows for digital processing and archiving of images. While CR images have improved quality over film, attention must be paid to potential increases in patient dose from retakes or higher than needed image quality. Digital detectors also have a wider dynamic range than film, allowing "good" images even if dose is excessive.

It works by using light-emitting diodes or lasers to project pixelated images in raster patterns onto the retina. Key advantages of VRDs include their small size, high resolution, wide field of view, and potential applications in areas like medicine, aviation, and augmented reality. Future developments may make VRDs more compact and affordable for widespread use.
Digital Radiography in Dentistry Seminar by Dr Pratik
Digital radiography involves capturing x-ray images digitally rather than on film. The document discusses the history of digital radiography from its origins in the late 20th century to current technologies. It defines key terminology used in digital radiography such as resolution, contrast, pixel size, and describes different types of digital x-ray receptors including CCD, CMOS, flat panel detectors, and PSP. Advantages of digital radiography over film-based methods are also mentioned.

DIGITAL IMAGING
Digital imaging involves capturing radiographic images digitally using various methods like computed radiography (CR), direct radiography (DR), or scan projection radiography (SPR). CR uses photostimulable phosphor plates while DR uses flat panel detectors, eliminating processing. Digital imaging provides advantages like improved image manipulation, reduced radiation exposure, and improved storage and sharing of images. Key types of digital radiography discussed are CR, DR, SPR, digital fluoroscopy, and digital subtraction angiography (DSA).
Dental Digital Radiography in Easy to Understand Steps
Dental Digital Radiography explained for better understanding and how it compares to regular analog radiographs.
Digital xray
Digital radiography uses digital X-ray sensors instead of film to capture images. There are two main approaches - direct sensors that directly convert X-rays to a digital signal, and indirect phosphor plates that store X-ray data and are later scanned to a digital image. Digital radiography offers advantages like immediate preview, no film processing, and ability to manipulate images. While initial costs are high, benefits include dose reduction, storage and transmission of images, and improved diagnosis through tools like contrast adjustment. Resolution is typically lower than film currently but sufficient for clinical use.
