Are there specific DICOM tags I’m neglecting that can be leveraged to preprocess before sending them to “reader.SetFileNames()”?Īny suggestions or guidance is greatly appreciated. This helped with some initial issues, but not the ones described above.

dcm by “acquisition time” and “series description” and/or “series ID” before feeding to “reader.SetFileNames()”. Series = #list of dicom file paths with common acquisition time and series description

Also, what should be the ends of the data sometimes appear in the middle, like a frame shift. I’m hoping someone else here has crossed this bridge before and may be able to share advice.įor example, there can be random few slices from the chest that suddenly appear in the abdomen (probably the images that were used for bolus timing). The approach I’m using is below and works great, BUT for some of the data the slices are not in the correct order due to something specific to the scanner might be writing to the meta data. I’m trying to convert a CT abdomen triple-phase dicom data folder into nifti 3D data by series.
