Minutes
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
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) XCA-I: Chris Lindop, Claudio Saccavini; request help from Rob Horn, Dave Heaney
5) Image Management Enhancements: Dave Heaney requested to undertake if profile to go forward
6) SWFII - Phase 2: Chris Lindop
