Concepts and relations to describe the process of DICOM deidentification

MIDOM - Medical Image Deidentification Object Model

A set of concepts and relations to describe the process of DICOM deidentification and a structured format for a deidentification protocol.

Why?

For projects related to DICOM deidentification, I'm running into the problem of not having the right words. I keep inventing terms, coming up with long-winded descriptions There is a lack of conceptual clarity. Lack of clarity causes:

• misunderstandings
• Ineffective communication
• misguided programming efforts
• wasted time generally.

The DICOM standard does not have enough detail. DICOM PS3 E-E1 gives thorough information on what to do to a single dataset, but not on how to reason or talk about multiple deidentifying processess, their differences, their characteristics.

For whom?

People developing or maintaining image deidentification pipelines.

What is it?

An information model first and foremost. Concept definitions with clear descriptions of their relations. There might be python code to define constants, transformations between objects maybe.

What is it not?

Anything that does any actual image processing. No loading of DICOM files anywhere.

For docs editors

Render html docs

Go to (in docs/build): make docs_html

Fancy auto-updating

Auto-reload a html view as you change the docs source. Requirements:

• Linux or WSL (this uses some subshell and piping tricks)
• entr - Run a command when files change. Apt install this
• livereload - Serve local files and auto-reload on change. Python lib found as dev dependency in midom.
• Possibly firefox to make livereload work properly

Steps:

• Start a shell in this midom base dir (where Makefile is)
• run uv run make launch_source_listener
• Open the livereload url printed in the script output. By default this is http://127.0.0.1:35729/

You might have to reload the page once to link livereload to the browser. After that, any save to a .rst or .puml file will trigger rebuild of docs/build, which will in turn trigger a page reload
