Technical Review of Image Sharing Profile Detailed Proposals
1) XDS-I_Using_XDS.b_Technology - Detailed Proposal: Paul Seifert
- Agreement on Summary and Problem Statement: impetus to update XDS.a-based provide and register transactions with XDS.b transactions
- Absence of specific guidance about XDS-I/XDS.b makes it impossible to test or claim compliance
- Consumer actor is required to support either or both DICOM SCU/SCP and WADO retrieve (integration statement does not indicate which capability system implements)
- Risk
- Development by DICOM WG10 of new DICOM Web Services transfer protocols may require further update to profile
- Open Issues
- Is it possible to avoid building in interoperability failures and invalidating existing implementations?
- Can these capabilities by added via CP instead of supplement?
- Timing issues: needs to be implemented quickly if it is to be of any use
- If it requires a supplement, can it be fast-tracked to allow 2009 deployment
- Can we make it possible to test XDS.b at 2009 Connectathons?
- Would need to inform participants and group together those willing to test this
- Need to review XDS-I metadata, which differs from XDS, and any changes required to upgrade
- Technical Proj Mgrs would have to develop specific testing requirements and plan: could add option ad hoc testing for XDS-I participants willing to try with XDS.b provide and register
- Participants willing to do XDS.b of XDS-I have already implemented XDS.a version
- Without way of publishing test results, there would be little incentive for vendors to go through the effort
- Need to carefully review the specific text changes proposed to understand their impact on compatibility
- Action Item: Chris Lindop will gather input from Canada Health Infoway about moving XDS-I from XDS.a to XDS.b
- Action Item: Gather input from ITI about XDS Roadmap and how to coordinate
- Effort Estimate (percentage of available Technical Committee bandwidth)
- Preliminary estimate could not be agreed on; to be addressed on 2008-10-09 tcon
2) PDI Extensions: David Clunie
- David Clunie updated proposal based on input by committee
- Proposal was written up as detailed draft in 2007 but not taken up by committee
- Scope
- Excludes use of MPEG
- Requires harmonization with other domains (Cardiology, Eye Care, Rad Onc)
- Risks
- Support for lossy compression is controversial, can lead to abuse
- Compression schemes: necessary, but raises bar and introduces controversy (eg, JPEG2000)
- Open Issues
- Security: rule out of scope initially; phase in later per user demand?
- Effort Estimate (percentage of available Technical Committee bandwidth)
- 15%
3) Basic Image Review: Kevin O'Donnell
- Kevin O'Donnell updated proposal based on input by committee
- Agreement on Summary and Problem statement
- Difficult issues in Key Use Cases impact difficulty of implementation by vendors:
- Comparison of series
- Localization of currently displayed image on orthogonal image
- Display of laterality of sagittal images (as distinct from orientation of image)
- Technical Approach is
- Mainly adds functionality to Image Display actor
- Scope of viewer capabilities to display complex modality images (eg, Nuc Med, ultrasound in scope?)
- Need to get input requirements from primary care physicians (neurosurgeons, orthopedic surgeons, etc): adds significantly to development workload
- List of candidate organizations and individuals to invite to meetings included in proposal
- Timeline goal is to be prepared for demonstration at AMA in April 2009
- Risks
- Difficulty of sufficiently engaging clinicians and vendors: need to work to get AMA Cmte, MITA Cmte and DICOM subcommittee, as well as DRG and RANZCR
- Work on getting input from referring physicians in US, Europe and Japan
- Need to define how evaluation will take place: objective criteria vs. judgment; clinical domain experts to be used as judges
- Action Item: RSNA will engage Media Creator vendors (and any vendors who develop image viewers for them)
- Open Issues
- Reporting should be kept out of scope: too large an issue in itself
- Effort Estimate (percentage of available Technical Committee bandwidth)
- 40%
4) Deferred to Oct. 9 Tcon:
- a. XCA-I: Chris Lindop will contact Claudio Saccavini to review initial draft developed by Kevin O'Donnell
- b. Image Management Enhancements: Chris Carr will contact Dave Heaney and request that he develop detailed version
- c. SWFII - Phase 2: Chris Lindop will develop scoped down version
5) Next tcons:
- New: Oct. 9, 10:00am - 12:00pm: Review remaining detailed proposals and provide effort estimates
- Oct. 13, 9-11am CDT Technical Review of Enhanced DICOM Objects Profile and other Detailed Proposals
- Oct. 22, Planning Committee Call to select profile list
- Nov. 10-13, Face-to-face Meeting (RSNA HQ) to begin profile development
