Objective
The aim of this project is to develop a methodology for rapid segmentation of knee structures from magnetic resonance (MR) images for subject-specific modeling. The overall goal can be broken down into two specific objectives -
1. Rapid segmentation of target structures into label maps.
2. Generation of simulation-ready models from label maps of individual structures.
Approach, Plan
Approach:
Multi-Contrast MR images are collected and seed points for each region of interest are taken as input. Cluster center and standard deviation are calculated for each ROI based on pixel intensities of the seed points. The pixels are clustered based on different pixel intensity values in multiple MR images to the nearest cluster center radius.
For detailed approach, please visit http://www.na-mic.org/Wiki/index.php/Stanford_Simbios_group
Plan:
a. Smooth the existing segmented label maps
b. Build models for bones and cartilage from the existing segmented label maps.
Progress
Finished segmenting different regions of interest like bones, cartilage etc.
Created label maps from existing segmented output.
