Introduction

This project contains a web server which accepts DICOM images and processes them with an ML model. Current models implemented are:

• Mirai
• Sybil

ark

Build Container

To build the Docker image for Mirai:

docker build -f docker/mirai.Dockerfile -t mirai .

Run Container

To run the published docker image:

docker run -p 5000:5000 mitjclinic/mirai:latest

After starting the container, you can test that it has launched with the following command:

curl http://localhost:5000/info

This should return something like:

{
  "data": {
    "apiVersion": "0.2.0", 
    "modelName": "mirai", 
    "modelVersion": "0.6.0"
  }, 
  "message": null, 
  "statusCode": 200
}

Submit images for prediction

The /dicom/files endpoint accepts a POST request containing multiple files. For example:

curl -s -X POST -F 'data={}' \
-F 'dicom=@mirai_demo_data/mlor2.dcm' \
-F 'dicom=@mirai_demo_data/mlol2.dcm' \
-F 'dicom=@mirai_demo_data/ccr1.dcm' \
-F 'dicom=@mirai_demo_data/ccl1.dcm' \
http://localhest:5000/dicom/files

With a larger number of files, it may be more convenient to have them all contained in a zip file. The /dicom/uri endpoint accepts a POST request of JSON content containing a direct link to a .zip file.

Valid JSON:

{'uri': 'https://directlink.com/file'}

Example CURL usage:

curl -X POST -H 'Content-Type: application/json' -d '{'uri': 'https://directlink.com/file'}' http://localhost:5000/dicom/uri

The structure of the .zip file must be similar to as follows:
