I/O (DICOM file -> .npy)

• Input data Directory
  • DICOM file extension = ['.IMA', '.dcm']

$ os.path.join(dcm_path, patent_no, [LDCT_path|NDCT_path], '*.' + extension)

The dcm_path directory should look like:

dcm_path
├── L067
│   ├── quarter_3mm
│   │       ├── L067_QD_3_1.CT.0004.0001 ~ .IMA
