The script is used to convert some kinds of DICOM data to regular images. Then you can annotate these images on CVAT and get a segmentation mask. The conversion script was tested on CT, MT and some multi-frame DICOM data. DICOM files with series (multi-frame) are saved under the same name with a number postfix: 001, 002, 003, etc.
