trying to get iso surfaces of a human-body parts such as ( bone, liver,
muscle, skin) from DICOM datasets. For extraction of iso surfaces, I'm
using the MarchingCubes algorithm, and it needs the Hounsfield Unit (HU)
for extraction. I've found many <span style="font-weight: bold;">different</span> HU scales for human body parts. My questions are;<br>1. In DICOM tags, there is a value called "RescaleIntercept" what exactly it is ? <br>is it an offset of CT dataset ? and if it is for example -1000, so what is the real HU of water for -1000 value ?<br><br>HUofBone = (double)DicomReader->GetRescaleOffset() + 1200.0;<br>boneExtractor->SetInputConnection(Dicomreader->GetOutputPort());<br>boneExtractor->SetValue(0, HUofBone);<br><br>In the given code, what GetRescaleOffset returns ? <br><br><br><br>
