In some DICOM files, slice position is not mentioned. However a calculated value is displayed in Radiant.
How is this calculated?

If the location tag is not available in the DICOM file, the image position tag is used:
(0020,0032) DS -108.300003\-97.400002\-117.559998 # 3, 34 Image Position (Patient)

RadiAnt calculates the COI (center of image) coordinates (in mm) and takes X, Y or Z, depending on which axis is closest to the normal vector of the image plane.
