Since the last post, I have made quite a bit of progress on writing the current version of the program.  The bone segmentation is complete which was a major milestone for triradiate air since it represents a completed stage 1 analysis.  Stage 2 is the individual bone segmentation and organ level segmentation.  The individual bone segmentation has been taken to a reasonable first pass stopping point and I am working on getting the small vessel tracking algorithms completed.

I have to say that there are very few algorithms that I write where the result vastly exceeds expectations to the point that only minimal modification is required.  The current version of the small vessel tracking is a significant departure from the SVT code that went into previous versions of the software.  Specifically, I have essentially abandoned the modified region growth algorithms all together.  The new algorithm is very similar to the iliac tracking algorithm in that it does not explicitly provide a direction for the vessel tracking to progress in, but rather it makes multiple attempts with varying starting points using the longest mean free path to guide it. 

At any rate, there is another major development in the ongoing Saga of Triradiate Industries.  The first server running an alpha build of the software has been installed at a major academic center and is being ported into the existing PACS system.  Hopefully over the next couple of months, we will get feedback and be able to modify the code base based on a more robust testing data set.  In the mean time, hopefully I can get the rest of the organ level segmentation completed.
