Limited capabilities to manually identify single slice Catphan® uploads using DICOM tag values have been added to the image processing system.  If the analysis type is selected in the upload widget dropdown or if the upload widget is set to a specific analysis, this will override the analysis type specified in the tags. If using tags to identify the analysis type, ensure that the analysis type is unassigned.

Figure 2.1: User interface when manually selecting analysis type.

Catphan® Analysis

Individual slices can be identified through modification of the DICOM tags to indicate the Catphan® module.

• For now, this feature will only work when the user uploads a single slice. It may get extended in the future (for example for things like the multiple slices generally needed for a CTP515).
• The software checks in the PatientID, StudyID and SeriesDescription tags.
  • The tags are checked for each image passed.
  • The tags are checked in the order above. If a match is found the search ends for the image.
  • If no match is found the automatic identification of the slice will be attempted.
• The matching search strings are case insensitive.
• Setting the module code does not guarantee the analysis will complete as a number of other factors come into play.

The following module codes are supported. Note not all modules are currently supported for display in Smári or TotalQA.
