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
• MR prostate registration from BRAINSFit to simpleITK
• prostate registration using BRAINSFit in Slicer 4.4
