At present ISAC has both a flow and an image file standard. The Flow
Standard FCS 2.0 is being upgraded to FCS 3.0. I believe that the practice
of Cytometry would be best served by joining with the American College of
Pathologists and the many other groups that are supporting the Digital
Imaging and Communications
in Medicine (DICOM) standard. The Draft for Public Review of DICOM
SUPPLEMENT 15, "Visible Light Image, Anatomic Frame of Reference, Accession,
and Specimen for
Endoscopy, Microscopy, and Photography;"
Source: American College of Radiology
American Society for Gastrointestinal Endoscopy
College of American Pathologists
American Dental Association
National Electrical Manufacturers Association
has been posted on the HL7 bulletin board:
http://dumccss.mc.duke.edu/standards/HL7/committees/image-management/DICOM/
This supplement states, "Comments are welcome and should be submitted to all
editors and to NEMA:" I believe that many of us in Cytometry can and should
comment on the microscopic image part of the standard. The next logical step
will be to extend DICOM to flow cytometry. I hope that the extensive domain
knowledge of the cytometry community will be utilized for this purpose.

>- Two modes of observation are supported
> Global impression -- i.e. Gestalt
> Feature search -- i.e. Region of Interest (ROI)
>- Two classes of Regions of Interest are supported:
> Named-ROI (arbitrary label applied to a region of "non-digital" evidence)
> Vector-ROI (region of digital evidence, e.g. image, waveform, described
>by a list of coordinates)
>- Image-related observations may be anchored to three "subject" categories:
> Person (and Named-ROI's of persons, e.g. abdomen, eye)
> Physical Evidence (and Named-ROI's of physical evidence, e.g.
>topographic regions of a biopsy specimen)
> Vector ROI
>- Observations may be expressed in four linguistic forms:
> Free text
> Categorical text
> Categorical coded entry
> Measurements
>- Modes of reporting:
> Manually, directly by observer (keyboard and/or graphical interface)
> Verbally in machine-readable form via a natural language processor
> Manually by gesture (tracing or pointing to a Region of Interest)
> By loosely or tightly structured voice dictation (recorded and
transcribed)
>- Observations may be linked to three types of procedure products (results):
> Related observations (e.g. the nodule measured 7 mm last month...)
> Related Regions of interest (e.g. the same configuration is evident in
>the left 2nd PIP joint....)
> Related Information objects (e.g. images, curves, audio, waveforms)
>- Summary interpretations and recommendations may be made:
> In an original report or amendment
> In tabular "log" format at the Results level (re: an original report
>and zero to many amendments)
>- Indications and historical summaries can be expressed
>- Physiological measurements may be described with LOINC codes
>- Two informative annexes are provided
> Entity relationships
> Structured reporting
>- The Service Group is defined in the first draft of the PS 3.4 (DICOM) Annex:
> CREATE
> GET
> SET
>- Here are some topics to be addressed in future revisions:
> Explicit specification of the digital and/or analog image(s) containing
>certain evidence
> Generic ROI relationships (supporting various relationship categories)
> Generic measurements-comparison, using a formal syntax
> Further revision of the SI and meta-SR Service-Object-Pair Classes
> First draft of the Interpretation Worklist (query/retrieve model)
> Additional historical summary sequences (e.g. problem list?, medication
>list?)
>
>Please comment. Your ideas are important.
