A user received some DICOM files from clinical software and the filenames had a non-ASCII dot character in the name (see attached image). vtkDICOMParser could not read these files. However,...

dicomtonifti.exe fails when dicoms in series differ in bit depth

4

dicometonifite.exe failed on series of dcm files from a Siemens Skyra MRI because the dcms on the extrema of the volume were 8 bits deep, but the majority of dcms...

Would it be possible to add an argument to dicomtonifiti that would allow users to set the "descrip" field of the resultant NIFTI header? It would help with de-identifying data,...

This CSharp example: https://lorensen.github.io/VTKExamples/site/CSharp/IO/ReadDICOMSeries/ Produces the following exception somewhat randomly: System.Exception: 'error: could not get registered type - mteIndex='4294967295' classNameKey=''' If you scroll through enough slices, eventually you should get...
