Hoffman2:Scripts:dcmheader.py

Purpose:

To view and edit a Dicom file header information or header of Dicom files under the same subject folder

Usage:

To use this script, you need to load python module first and export the library location:

module load python/3.6.1_shared
PYTHONPATH=/u/project/CCN/apps/python_libs/3.6/site-packages/

To see the usage of this script

python3 /u/project/CCN/apps/scripts/dcmheader.py -h

Options:

--print (or -p)

Showing the full header of a dcm file python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/file -p (or --print )

(This option can take only a single dicom file as argument)

Example of a part of the output from option --print

(0010, 0010) Patient's Name                      PN: '12345'
(0010, 0020) Patient ID                          LO: 12345
(0010, 0030) Patient's Birth Date                DA: '20000101'
(0010, 0040) Patient's Sex                       CS: 'F'
(0010, 1010) Patient's Age                       AS: '020Y'

(0010, 0010) is the tag for item “Patient's Name”, you'll need this information for using -c (--check) and -u (--update) options.

-c (--check) option: This option is to view specific header items in a dcm file or the same items in all files inside the subject folder

View a single item: python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/subject/file -c "(0010, 0010)"

View a single item in a subject folder by specifying the folder instead of a file: python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/subject/ -c "(0010, 0010)"

View multiple items: python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/subject/file -c "(0010, 0010) (0010, 0020)" python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/subject/ -c "(0010, 0010) (0010, 0020)"

-u (--update) option: This option is for updating specific header items, using the format as "tag=new_value" Example: update a single item (in this example, change the Patient's Name value to 12345_1): python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/subject/file -u "(0010, 0010)=12345_1" update the same item for the whole subject folder python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/subject/ -u "(0010, 0010)=12345_1"
