Hi to all,

I have the following problem with an MR Spectroscopy Dataset in DICOM
format how to "calculate" the patient's orientation:
The DICOM tree has the following output:

(0020,9116) SQ [PlaneOrientationSequence]:<Sequence tag. 1
sequenceItems, 0 values>
Sequence Item 0:
(0020,0037) DS [ImageOrientationPatient]:0.999659

There is indeed only one value at "ImageOrientationPatient". I would
have expected to 3D-vectors ("the direction cosines of the first row
and the first column with respect to the patient")
How could this value be interpreted ?
First I thought of (0.999659/0/0/0/1/0), but that is completely wrong,
due to the visualization of the data. There is a (small) rotation in
there.
I would by thankful for any suggestion or hint.
Kind regards,
Bernd
