QIBA FDG-PET/CT Software Version Tracking Technical Subcommittee Charge
- The objective of the subcommittee is to track the traceability of SW version of a PET/CT system to ensure the consistency of quantitative output throughout the trial
- Rationale: Due to the continuous improvements of current PET/CT systems, vendors will upgrade software in different part of sub-systems from time to time for the same system. Some of upgrades will include quantitation improvements.
- Essential SW to be tracked: Three major SW in the quantitative imaging chain should be tracked: Acquisition (include detector), Reconstruction (may be combined with acquisition) and Quantitation Tool*
- Approach:
- Current: Manual Tracking (available now);
- 5-8 Years: Fully DICOM Tracking (New DICOM attributes needed);
- 8 Years and Beyond: One-button SW Tracking Function (Industry guideline - vendors to do it)
- Note: * Some sites use third party Display/Quantitative Tools, which further complicate the tracking
1. Current: Manual Tracking
- Status: Currently, every vendor should have the ability of obtaining the version info for each software program/application installed.
Action: Send out a survey to vendors for instructions to check the SW version (Acquisition, Reconstruction, Quantitative Tool. Some vendors provide multiple reconstruction methods)
2. Fully DICOM Tracking (5-8 Years)
- Status: Currently only the attribute for acquisition SW version may exist
- Action: Work with other committees to define a global recommended list of DICOM attributes needed for quantitation purpose
- Working with DICOM committee to define the timeline for implementing the list
3. One-button SW Tracking Function (8 Years and Beyond)
- Status: Currently, vendors provide tools to view all/most DICOM Info, but, most info which impact quantitation are missing (No DICOM Attributes): The goal is for vendors to provide a one-button function in the quantitative tool to display all quantitative related info.
*Action:
- 1.Define what are the quantitative info to be recorded (DICOM)
- 2.Develop guidelines (working with NEMA ?)
- 3.Compliance Steps
