MicroView 2.5.0 alpha10 is now available from our website for win32, win64 and OSX platforms.  The Mac version no longer requires X, which is helpful if you run Mountain Lion 10.8.  There's two new plugins to try out, as well as the return of the basic bone analysis app.  Let us know what you think.  See http://www.parallax-innovations.com/microview for all download links to this pre-release version.

Thanks to our friends at Endra Inc., we've had an opportunity to involve ourselves in GPU-based algorithm acceleration. This has ended up, for us, being a substantial deep-dive into technologies such as CUDA and OpenCL, but with significant results. The advantages of GPU acceleration over conventional computing are well known, even in the face of impressive improvements in generalized CPU multi-core capabilities in recent years. These advantages are especially true in the medical imaging field, where almost all compute-intensive tasks in the imaging pipeline are embarrassingly parallel. CT reconstruction is one example that we've chosen to focus on recently - we've started by implementing a flexible GPU-accelerated CT reconstruction framework, that can act as both a platform for algorithm design and development, as well as a de facto replacement for legacy CPU-based reconstruction engines. At the moment, it is capable of reconstructing scan data from GE's Locus, eXplore and Ultra CT products - depending on reception, we may choose to port it to more systems. Our reference implementation uses the well-known stock Feldcamp conebeam backprojection algorithm and is written in python for maximum flexibility. It uses pycuda for the heavy lifting. See below reconstruction results from a variety of platforms -- of particular interest, perhaps, is the NVidia GTX 580 results, for sheer speed, and the NVidia GTX 460M, which is running on a laptop. The latter results compare favorably against a 9-computer beowulf cluster, showing just how far GPU technology has come in recent years. The results are preliminary, and will be updated frequently as our recon engine improves and is tested more widely.

(Note: It seems that the interactive graph does not show up, if you are viewing with Internet Explorer. We apologize for that, but for now, you will have to use one of the other browsers, if you wish to see the results).

Many thanks to Dr. Terry Peters for inviting us to the recent Slicer3D workshop, held at UWO today, in conjunction with the J. P. Robarts Research Institute.  The workshop was a hands-on tutorial of a pre-release version of Slicer3D from an end-user's perspective followed by an introduction to the application from a developer's perspective.  Since both VTK and ITK are exposed directly via both TCL and Python wrappers, the application is a pretty short putt from what we've worked on in the past.  We'll continue to examine Slicer3D for visualization opportunities.
