Project Description

Objective

  • Design an easy to use GUI for ProstateNavigation (Planning, Registration, Navigation)
  • Get ideas how prostate segmentation can be done quicker, fully automatic in best case
  • Validate different pre-op to intra-op registration approaches

Approach, Plan

  • Create mockup GUI
  • Try to use existing segmentation modules like Robust Statistics Segmenter or VolumeClip for quicker prostate segmentation
  • Evaluate the segmentation results (DICE-Coefficient) by comparing to manual segmentation of trained radiologists using this dataset
  • Evaluate pre-op to intra-op registration with General Registration (BRAINS) module in Slicer 4.4

Progress

  • Created requirements list containing the core functions of the workflow
  • Created draft of the GUI with its necessary components
  • Best solution for prostate segmentation seems to be VolumeClip Model (under 15 seconds user interaction time)
  • Started evaluation of BSpline registration in BRAINSFit module with masks
  • Convert prostate registration of BRAINSFit to simpleITK
