I. Welcome and Introductory Remarks; Introduction of Participants
Dr Horton welcomed the participants. Everyone introduced themselves and their
affiliation.
II. Approval of Previous Meeting Minutes
The minutes of the October 21 2011 WG9 meeting in Orlando were approved.
III.
Major discussion items:
1
A)
Review of progress since October 2011
1. Corneal Topography Supplement, Dr. Stephen Klyce
Dr. Horton described the activities of the Corneal Topography workgroup.
The critical issue for the workgroup now is whether to include topography, as
originally intended, or to have the scope solely on corneal topography so that
the supplement can be focused. The input of the WG9 was that it seemed
more feasible and better in the long term to focus the scope on a more and
doable topic as corneal topography, as had been done in the case of
ophthalmic thickness mapping. This will be relayed and discussed in the
meeting of the Corneal Topography workgroup.
2. Ophthalmic Axial Measurements IOD (Supplement 144)
Don Van Syckle reported that there were a few corrections that were needed in
Supplement 144, Ophthalmic Axial Measurements, but these did not affect the
technical content. Developers should still use the Final Text Supplement 144,
until such time that the editorial changes have been made.
3. Ophthalmic Tomography IOD (Supplement 110)
Don Van Syckle reported that David Clunie had raised an issue with
Supplement 110, Ophthalmic Tomography. The issue is the absence of the
VOI LUT module. Members of the group offered various perspectives. Rich
Amador thought that this should be treated like any other monochrome
DICOM image, and should have a VOI LUT module. If the Supplement 110
specifies only an 8 bit object, then the VOI LUT module is not possible.
Another issue that came up was the consistency across the ophthalmic IODs.
Yijun Huang volunteered to look across all of the IODs to identify any
inconsistencies. One more issue suggested by Claudia Wasch in the prior email discussions was to reference a prior study in order to look at changes
over time. Don Van Syckle noted that this was already covered in DICOM
and this seems adequate for this use case. Yijun Huang is going to draft a note
for this use case as a Correction Proposal to clarify this for developers. A
group will investigate the issue of the VOI LUT further. This group will be
led by Yijun Huang, and consist of the following members: Michael Reutter,
Artur Kowalski, Tobias Kurzke or another individual from Zeiss.
B)
Ocular imaging challenge grant
The Academy worked with the Office of the National Coordinator of Health
Information Technology to define an ocular imaging challenge grant to show
interoperability based on the DICOM standard. This was publicized to the WG9
community when the announcement was made. The deadline is November 11th.
C)
Meaningful Use Stage 2 Proposed Rule
The Academy DC office and the Medical Information Technology committee
worked to promote specific ophthalmology-specific issues for meaningful use
stage 2, including interoperability with DICOM as a specified certification
2
standard. This standard was included in the proposed rule, but was not included in
the final rule. Hopefully, this will be included in stage 3 of Meaningful Use.
D)
How to increase implementation of DICOM standards
This is a recurring topic because although there has been broad uptake of certain
supplements, Ophthalmic Photography and Ophthalmic Tomography, several of
the more recent supplement don’t appear to have been implemented, e.g.,
Refractive Measurements, Visual Fields, Axial Length Measurements, and
Ophthalmic Thickness Mapping. The group offered some suggestions to help,
one of which is to resend the Academy’s survey to device vendors and image
management vendors and publish those who have responded, and names of
companies that the surveys were sent to. Another suggestion was to find
individuals at the companies in marketing and sales positions to convince them of
the value of IHE. Another suggestion was to publicize the Veteran
Administration’s policy of requiring DICOM conformance to those vendors who
are not yet aware of it.
E)
Freeware DICOM viewer
Yijun Huang announced that there was an available revision of the freeware
DICOM viewer developed by the University of Wisconsin Reading Center and
partially supported by the Academy.
IV.
New work items
A) The group discussed the use case that an ophthalmologist would like to see a selected
image from the past to provide reference and comparison to a current image. This
will need some effort by a dedicated workgroup to look at what is available in
DICOM standards already. All those interested in working on this topic should
contact Flora at [email protected].
