Image from CT data downloaded from http://graphics.stanford.edu/data/voldata/
Okay, this is a bit gruesome, but I’ve been dusting off some old papers that I never really understood on Fourier Volume Rendering, and testing my understanding by writing some simple code that takes in a volume dataset and uses the fast Fourier transform to convert it into simulated X-ray pictures. The data set that this picture was generated from was downloaded from this webpage at Stanford, and consists of CT scan data of a cadaver. The basic code works! Given a bit more work, I should be able to do arbitrary orthographic views.
The math for all this is described quite admirably by Tom Malzbender’s paper Fourier Volume Rendering.
