Objective

We are developing methods for automatically detecting post-procedural scar in LGE-MRI images. The goal is to make statistical group comparisons based on the spatial distribution and amount of scar.




Approach, Plan

Our approach for automatic scar segmentation is summarized in the SPIE 2012 reference below. Briefly, we are using k-means clustering to tease apart the normalized pixel intensities corresponding to different tissue types (e.g., healthy, scar, blood).

Our plan for the project week is to test our module, and ensure that it meets "Ron's Rules" and develop supporting documentation/examples. We will present a tutorial on this module during the project week tutorial contest [1]

Progress

Software for the automatic scar segmentation has been implemented [2]. We have created documentation/tutorial for the module. Lastly, we have updated the acknowledgements section to include the appropriate logos and information.


Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a

  1. ITK Module - NO
  2. Slicer Module
    1. Built-in - NO
    2. Extension -- commandline - YES
    3. Extension -- loadable - NO
  3. Other (Please specify)
