BioTIFF Overview
What is TIFF?
TIFF (Tagged Image File Format), is Aldus-Adobe’s Public domain tag-based file format for storing and interchanging raster images.
TIFF is a rich format for pixel based raster image data from many sources
still and video cameras
monitor screens
scanning and rendering output from medical imaging
other medical diagnostic instrument
results of simulations and mapping.
other image file formats
Multi-Page TIFF File Structure
Uses offset pointers to link Image File Directories (IFDs) that identify and locate specific sets of image data and meta data (pages).
IFDs consist of lists of TIFF Tags and an offset pointer to the next IFD
Tags contain: 1) identity code 2) data type code 3) number of values associated with the tag and 4) offset to where the data is found
Each page has its own IFD and can be located anywhere in the file
TIFF has remained stable since 1992.
Standard TIFF uses 32 bit offsets giving a maximum size of 4G
The Big TIFF project will use 64bit offsets enabling one file to contain 16 ExaBytes (16 Million TeraBytes)
see : www.awaresystems.be/imaging/tiff/faq.html#q3
The GeoTIFF represents the efforts by over 160 different remote sensing, GIS, cartographic, and surveying related companies and organizations to establish TIFF file format based interchange format for geo-referenced raster imagery.( http://www.remotesensing.org/geotiff/geotiff.html )
GeoTIFF exploits the self-documenting properties of geographical coordinate systems to uniquely identify locations within a GIS image and allowing cross-referencing to other related information artefacts.
The BioTIFF seeks emulate the success of GeoTIFF by establishing a TIFF file format based interchange format for bio-referenced raster imagery. Like GeoTIFF It is an open source community based project

BioTIFF is file specification designed to provide a:
container for related clinical and personal information needed to interpret each diagnostic event co-localizing meta-data with primary data
means for remotely accessioning, curating and reusing original data and interpretations, assuring their provenance and enabling distributed usage
means of asserting ownership over diagnostic information.
means regulating and monitoring access through encryption and tagging
means for tracking health care trajectories and creating personal narratives of the experience
communication bridge between data owner and care provider supporting dialogue concerning shared understanding of goals and experiences
beacon for secondary use applications and social networks
(Topic) Specific bio-medically definable (biomarkers, vital signs) health (Context/Community) diverse stakeholders & caregiver perspectives and sense making (Task) adapting health care system to patient needs BioTIFF will Enable Personal Health Narratives and Collaborative Evaluation of Health Care Trajectory

Personalized Narrative Diagnostic Imaging: Can it Mediate Patient/System Dialogue An extension of medical imaging systems to supplement biophysical data with socio-technical data concerning the patients experience and world view as well as their goals of care ; Chap 6: Pennefather and Suhanic in: Mediating Health Information The Go-Betweens in a Changing Socio-Technical Landscape Edited by: Nadine Wathen, Sally Wyatt and Ronna Harris http://www.palgrave.com/products/Title.aspx?PID=285092
ISO defines an EHR as “a repository of patient data in digital form, stored and exchanged securely and accessible by multiple authorized users. It contains retrospective, concurrent, and prospective information and its primary purpose is to support continuing, efficient and quality integrated health care”. A PHR is an EHR where the data in the record is controlled by the patient and contains data at least partially entered by the patient (ISO) National EHR system standards like Health Infoway aim to ensure that EHRs are 1) patient centric and engage/empower patients; 2) share common core information fields 3) use common standards for encoding those fields; 4) are secure and protect participant privacy; 5) are open, transparent, interoperable. They may be: 1) time oriented, 2) source oriented or 3) problem oriented . Can they be Narrative Oriented
Beyond a Record of Healthcare Data – Towards a Narrative of Healthcare Meaning A key aspect of health care self-management is making sense of and owning personal health care information and data Sense/Meaning/Credibility/Relevance only exist within the context of a community that shares information An authentic personal narrative of health care meaning is defined dialogically within a community (e.g. the circle of care)
Health Care Meaning and PHRs
Records used in problem solving contain: Subjective information , Objective information , Interpretive Information (e.g assessment/diagnosis/synthesis/conclusion/speculation); Action/Management Plan Information Outcomes Information .
Objective Patient Summary Information Records like CCR contain: history which can be further divided into; identity/custody/relationships administration (admission/referral details, plan, access rights, etc.) past medical history, social history (life style/occupation/social status, e.g. level of poverty), stage of care (acute, chronic, palliative, end-of-life); population parameters (age, gender, culture, cohort, disabilities, immunities/vaccinations biological idiosyncrasies [e.g. allergies,, mutations etc]); test results (lab med, imaging, physical exam, vital signs, biomarkers, cognitive, social) active problems/diagnoses ; medications/treatments , proscribed (guideline/pathway/label appropriate) non-proscribed/experimental primary, secondary; assistive/palliative ; alternative/complementary
How is it used.
Documents objectives/goals/intentions of care (best practices)
Documents delivery of care (from the patients perspective in the case of the PHR)
Documents outcomes/experience/continuity of care
Provides a patient authorized channel for secondary use of personal health care information for:
Many ways of implementing PHRs and it is not possible to generalize functionality. But there are a subset of platform independent ways of evaluating function in terms of : 1) information, system, and service quality (consistency, relevance, completeness, timeliness, accessibility); 2) information accuracy, usability, and applicability 3) user satisfaction/experience; 4) impact at individual and community level Specifications
