Operating system: Windows 7
Slicer version: 4.8.1
Expected behavior: Convert to grayscale
Actual behavior: Cannot load as a scalar volume
I have PET images that I want to get the SUV values from certain ROIs. However, I cannot load the DICOMs in because they are RGB instead of grayscale. Is there a way to convert this to grayscale? So far I see the “Vector to Scalar Volume” module, but this appears to be for images (.jpg, .png, etc).
I converted my PET to grayscale in MATLAB but I am not confident in the transfer back to Slicer. Is there an easier in-house method for the DICOM files?
