CP-1648 Correct requirement for conversion source in legacy converted images and tractography results Status Final Text Date of Last Update 2017/04/18 Person Assigned David Clunie Submitter Name QIICR Submission Date 2016/08/17 Correction Number CP-1648 Log Summary: Correct requirement for conversion source in legacy converted images and tractography results Name of Standard PS3.3 2017a Rationale for Correction: The Image Frame Conversion Source Macro is required to encoded the SOP Instance UIDs of the images from which the converted instances were converted, but this requirement precludes the use of the IOD for images that have been converted from another format. Make the requirement conditional. The Tractography Results Module also requires the Referenced Instance Sequence, which precludes the use of the IOD for tractography results that were not created from DICOM images (whereas tractography results may be created from proprietary format images).
