I do have DICOMs (Digital Images and COmmunications in Medicine) from several CT volumes where most volumes miss the SliceThickness and SliceLocation attribute.

Is there another attribute usually contained in a DICOM which tells me something about the length or height of the total scan?

The goal is to approximate the SLiceThickness - any means are much appreciated!

  • Welcome to MedicalSciences.SE. In order to help, I have edited your question to make it more clearer. When using acronyms, please can you define the abbreviation as described in this meta post to help those who may not know what you mean? Aug 15 '19 at 5:55
  • Thanks for the edit and reference @Chris Rogers will do in the future

  • @ChrisRogers I think the edit is fine but probably not necessary here; DICOM is an image storage standard. It's a bit like words like "laser" where far more people would know the name DICOM than be able to recite what it spells out. DICOM itself is effectively a proper noun. Aug 15 '19 at 16:13
  • @BryanKrause - The point I was making, as pointed out in the linked meta post, not everyone will know what DICOM is. I didn’t until I looked it up. Commonly used acronyms such as AIDS shouldn’t need spelling out, but less common ones need defining for those who may not know. I seem to remember though a case where STI was thought of as illness rather than infection. Aug 16 '19 at 8:52

    I added a link to help clarify. I often will do that instead of just putting in what the acronym stands for, since often that doesn't make it any clearer to those who aren't already familiar with the specifics. Unfortunately I don't know the answer; although slice thickness is a key attribute of a CT scan, and that should be accessible somewhere in the CT data, I am not familiar with the standard conventions for where that information is stored in CT records.
