wrong dose matrix resolution

Open richardmuellerx opened this issue 9 years ago • 5 comments

The display of isodoses of a DICOM RT Dose file is not correct if the resolution of the dose matrix is not equal in row and column direction. Please have a look at the DICOM Image Plane Module, tag Pixel Spacing (0028,0020). The attribute description says: "Physical distance in the patient between the center of each pixel,specified by a numeric pair - adjacent row spacing (delimiter) adjacent column spacing in mm. See Section 10.7.1.3 for further explanation. I suspect that the row and column spacing are switched in the dicompyler implementation.

Great, this should be relatively easy to fix. Do you have any sample data so we can add this to a test case?

Yes, but how can I send it to you?
