Using DICOM attribute information to determine the range of bone pixel values


I'm working with DICOM CT images to segment bones. I was wondering if I can use DICOM attribute information to determine the range of bone pixel values.


Solution

  • Chapter 3, Annex A.3 of the DICOM standard [1] specifies the IOD for the CT dataset. It consists, among others, of the Image Pixel Module (C.7.6.3). The Pixel Module has two attributes "Smallest Image Pixel Value" (0028,0106) and "Largest Image Pixel Value" (0028,0107). However, these are Type 3 attributes and might not be present in your dataset.
