The itk coordinate system is lps, and the slider is ras. However, why does the cursor on the slider display coordinates that are not actually ras? For example, the dicom coordinates are (1, 1, 1), while the actual coordinates in the slider are (-1, -1, 1), and the slider cursor displays coordinates that are (1, -1, 1)
I am speculating, but that’s probably related to some other radiological convention being used. Reported measurements are still consistent, but as you said it is neither RAS, nor LPS, but LAS (look at the wording on the title bars Green is A, Red is S, and yellow is L).
Just a small observation here: when I called the first versions of Subject hierarchy “Patient hierarchy” it was deemed not appropriate because Slicer is not strictly for use in humans. Just as demonstrated here in this topic - the images are pre-clinical. In the same spirit I don’t think we should call these options “patient right is screen left” etc, but use the word “subject”. @pieper@lassoan
For pre-clinical images that use DICOM as the file format, is it standard to use “Patient” instead of “Subject” or “Animal”? I’m not familiar with the usage of pre-clinical image metadata in DICOM format.
