Units displayed as RAW in TMTV mode rather than PROPCNTS[Bug]

Open BrandonDatUHN opened this issue 1 year ago • 3 comments

Describe the Bug

When viewing a measurement on an NAC/No PT weight in TMTV mode the units of the measurement are displayed as "RAW" instead of prop counts/BQML as they are in Basic Mode.

On OHIF demo : https://viewer.ohif.org/tmtv?StudyInstanceUIDs=1.3.6.1.4.1.14519.5.2.1.7009.2403.871108593056125491804754960339

In TMTV mode image In Basic mode image

On OHIF demo/local with a PET AC with no patient weight: In TMTV mode image In Basic Mode image

Steps to Reproduce

  1. Select a PET-CT from the list on the OHIF viewer demo eg https://viewer.ohif.org/tmtv?StudyInstanceUIDs=1.3.6.1.4.1.14519.5.2.1.7009.2403.871108593056125491804754960339
  2. change to the NAC PET image (ignore the fact that sagittal and coronal turn grey/black that's https://github.com/OHIF/Viewers/issues/3758)
  3. draw an ellipse ROI on the axial panel of the PET NAC
  4. measurement is displayed in "RAW"
  5. go back to studies and open the same study in basic mode https://viewer.ohif.org/viewer?StudyInstanceUIDs=1.3.6.1.4.1.14519.5.2.1.7009.2403.871108593056125491804754960339
  6. select the NAC and draw the same ellipse and the units will be in Propcounts

The current behavior

The units displayed for PET images which are not SUV calculable (no patient weight or uncorrected) are displaying measurements in "RAW"

The expected behavior

The units displayed for PET images which are not SUV calculable (no patient weight or uncorrected) should be displayed in whatever units are listed in the dicom meta data under the "units" tag. PROPCOUNTS for most NAC and BQML for most PET AC, This is the behaviour in basic mode

@BrandonDatUHN is this still an issue with the most recent viewer-dev?

Yes this specific bug still exists on dev viewer.

Open the water phantom in TMTV, drag the NAC onto the PET section, use the measurement tool, units show as RAW.
