Hi, my name is Kyle Champley. I've worked my entire career on tomographic imaging (CT, PET, and SPECT). Currently I work atZiteo Medical where I am leading a team in developing a novel high-resolution SPECT system. Previously, I worked atLLNL in theNondestructive Characterization Institute working on x-ray and neutron CT. I've also worked in the CT group at GE Global Research and consulted/ contracted for several medical imaging companies, includingPET/X,Imatrex, and Precision Sensing. I have a PhD from the University of Washington under the supervision of Paul Kinahan and Tom Lewellen. I am a mathematician by training, but these days I mostly do scientific computing.

Here on github I contribute to theLEAP-CT,XrayPhysics, andLEAPCT-UI-GUI software packages.

I'm happy to provide support for any of these open-source projects, but if you're in need of extra help with your tomography data, I can provide further assistance as a paid contractor. Please contact me by email (champley@gmail.com) and we can work out the details.
