from ifree import dicom

# get paths for CT, MR, DOSE and RT
fileDir = "./p/"
ctfiles, rtfile, mrfiles, dosefile, patientID = dicom.GetFilePath(fileDir)

# get MRs or CTs related to RT and copy them to new dir
patientNames, patientIDs, id2mrs, id2rt = archiveFiles(old_Dir, new_Dir)

# crop ROI-MASK and its CT or MR
roiName = "ctv"
newDir = "./p/"
newSize = [100, 100, 100] # leave None to get origin size
cropROI(id2mrs, id2rt, roiName, newSize, newDir)
