Describe the bug. What happened?

Hi,

I am using weasis 4.4.0 with Windows 11.

Here's what I do:

  1. open a dicom series
  2. open MPR
1

The slice number of a sequence in MPR mode seems reversed: 2

I am not sure if this is a bug or by design.

What version of Weasis are you running?

4.4.0

On which system the problem occurs?

Yes, it is an issue. The sorted order is reversed for all the directions.

After analysis, this is not a bug but simply a sorting according to Anatomical Direction that is forced in MPR mode.

Anatomical Direction is defined in DICOM the x-axis is increasing to the left hand side of the patient. The y-axis is increasing to the posterior side of the patient. The z-axis is increasing toward the head of the patient.
