  • Knee MRI Image

  • Pre-Segmented Femur/Patella/Tibia Model.

  • EM Segmented Output.

Objective

The aim of this project is to develop an automatic/semi-automatic methodology to convert whole body imaging datasets into three-dimensional models for neuromuscular biomechanics and finite element simulations.

Approach, Plan

We focus on developing library of atlases for specific joints (eg: the knee) and evaluating EM Segmenter Algorithms. The main challenge during this process is the study of techniques for registration of a patient MRI image to a given patient MRI image (for which we already have atlas). Our approach to achieve this is to conduct parameter exploration study using the module Register Images Batchmake in Slicer 3.4

We are also investigating another technique where we try to register a given knee model to a patient MRI Image using Python ICP Registration.

Our plan for the project week is to 

 a. Perform and evaluate results from an extensive 
 parameter space exploration study of 
 RegisterImages Batchmake module on knee dataset.
 b. Resolve issues in building Python modules from 
 slicer source code.
 c. Demonstrate proof of concept on registering an 
 existing atlas (.vtk, .stl) to a target image 
 using Python ICP Registration module.
