How can I use the DICOM tags (US Region sequence or pixel spacing value) together with the TImageEnVIew.SetScaleFromPixels() function to accurately perform measurement in a medical image?
OK, so the tags in your DICOM image specify the scaling as follows:
(0018,6024) Physical Units X Direction (US) : "3" (0018,6026) Physical Units Y Direction (US) : "3" (0018,6028) Reference Pixel Physical Value X (FD) : "0.000000" (0018,602A) Reference Pixel Physical Value Y (FD) : "0.000000" (0018,602C) Physical Delta X (FD) : "0.011576" (0018,602E) Physical Delta Y (FD) : "0.011576"
(You can view tags using the demo: Demos\InputOutput\DicomTags\DicomTags.dpr).
The values for "Physical Units X Direction" are defined at:
