If the Image Orientation (Patient) tag (0020,0037) reads [1,0,0,0,1,0] and the Patient Position tag (0018, 5100) reads ‘HFS’, how do I interpret Slice Location tag (0020,1041), assuming that it exists? I know that it represents the `Relative position of the image plane in millimeters', I'm just having trouble relating the end points of the range to the Z axis in the DICOM Reference Coordinates System (RCS).
Example: I have an sequence of Slice Location numbers in the range: [-1873.382, -771.782]
Since the numbers are increasing and in the DICOM RCS, the Z axis increases in the Inferior to Superior direction, can I conclude that '-1873.382' is the position of the most Inferior slice?
Also, just to note that the z coordinate of my Image Position (Patient) (0020,0032) attribute for each slice, contains the same information as my Slice Location tag.
