The use case for converting to DICOM _could_ be : 1.) standard based "image" storage and sharing 2.) image manipulation with standard (any) DICOM viewer out there Tools like this make the conversion process easy https://support.dcmtk.org/docs-dcmrt/img2dcm.html[1] or this https://github.com/pydicom/pydicom/issues/939[2] -------- [1] https://support.dcmtk.org/docs-dcmrt/img2dcm.html [2] https://github.com/pydicom/pydicom/issues/939
