Photon Mapping using Historygrams
Medical modalities such as CT scanners are generating increasingly large data. In just a few seconds thousands of 2D slices can be extracted and be put together to a volume of data representing the human body. Researchers in ELLIIT have developed new methods for ultra realistic volume rendering of this data. The illumination of the data is based on tracing of virtual photons that are allowed to scatter in the participating volumetric media. This generates images with realistic light conditions such as shadows and gloss. The computational complexity of tracing photons is reduced by using novel data representations which take into account which photons that are affected by changes of visualization parameters and "remembers" the path of the photons. We have named these data structures "Historygrams" and for the first time we can achieve interactive interaction with ultra realistic volume rendered images. The work will be presented at the upcoming IEEE Visualization conference in Seattle in October 2012.
