dicom-standard-parser

Parses the most recent DICOM standard into two easily-consumable JSON files with a single command.

Usage

Takes an optional list of IODs to include in the output. If none are provided, every IOD from part 3 of the standard is included:

npx dicom-standard-parser "CT Image" "RT Structure Set"

Output

Outputs two files into the directory in which it's run:

data-dictionary.json

JSON version of part 6 of the standard. One large object whose keys are tags and whose values are the keyword, VR, and VM columns from the standard.

{
    "20000010": {
        "name" : "NumberOfCopies",
        "vr" : "IS",
        "vm" : "1"
    },

IODs.json

JSON version of part 3 of the standard. Consists of an object that has iods and modules
