In addition to Volkmar's excellent toolbox find enclosed 2 attachments of the
siemens handbook(s). As I have searched quite a while myself it's not that
easy to find. These Infos are from an Allegra System. It should be consistant
over all topical Siemens Scanners though.
The pdf page is german but I think the vector table is understandable. the
coloums are:
sequence nr of images (0-5 for 6, 0-11 for 12 directions)
the vector directions for 6
the vector directions for 12 images
What is x,y,z is explained in the jpeg image.
Hope this helps.
