Synthetic images, vector fields, RT structures and RT doses in Slicer and ITK

Figure out the best representation in ITK and Slicer4 for various RT and related datastructures.

Objective

We are designing synthetic DICOM-RT dataset which includes CT image, structure set and dose distribution. The following guidelines are used. We measured the noise power spectrum of a real CT image and constructed synthetic image with exactly the same spectrum. Then we included "skin" and one internal spherical structure. Synthetic contours were generated and recorded in labelmap format. Synthetic dose distribution was generated in mha format.


Approach, Plan

Currently synthetic DICOM-RT is loaded into Slicer 3.6.3 from file through Plastimatch extension DICOM/DICOM-RT Import. We plan to build Plastimatch command line module that will allow us to create synthetic image, structures and dose distribution interactively according to user's needs.

Progress

  • Discussed the use of Slicer4 hierarchies to group structure sets
  • Reviewed DICOM networking interface with respect to RT workflows
  • Worked around resampling performance issues with itk vector images

Delivery Mechanism

This work will be delivered to the NAMIC Kit as a

  1. NITRIC distribution
  2. Slicer Module
    1. Built-in: perhaps RT support can become part of MRML
    2. Extension -- commandline: Maybe, if needed
    3. Extension -- loadable: yes, for a custom interface
