Calculated slope value without dicom attribute
Hi, I have a problem with a dicom series (see attachment) whose
files don't have the rescale slope/intercept attributes.
Nonetheless, dcm2niix calculates a slope value of 7.2.
I thought it was related to this thread, so I tried passing the "-p n" option, but dcm2niix always reports the same value.
I'm I doing something wrong?
Thank you.

RE: Calculated slope value without dicom attribute
The intensity slope is from DICOM tag 0040,9096
RealWorldValueMappingSequence, see C.7.6.16.2.11.1.1 Real World
Value Mapping Sequence. The Philips precise option has not effect
as these vendor specific values are not provided.
