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.


--check (or -c)

View specific header items in a dcm file or the same items in all files inside the subject folder. You will need to specify the header tag as the argument in format as (code1, code2), however the parentheses are not required. Multiple tags can be specified as the following example

Example:

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 of a single file:

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

View multiple items of all files under one subject folder:

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

--update (or -u)

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 every files under the same subject folder

python3 /u/project/CCN/apps/scripts/dcmheader.py -f /path/to/my/dicom/subject/ -u "(0010, 0010)=12345_1"
