fMRI visualization of multiple functional areas

Abstract

The reconstructed scan data consists of a volume dataset for each activation area as well as the anatomy and vasculature (blood vessels). We display the anatomy and vasculature to provide context for the activations. In hardware that is two texture reads and two dependent (LUT) reads. Naively, each activation volume requires a texture lookup and two dependent reads. Display of three activation areas requires 13 texture reads, 3 serial pixel subtractions and 4 additions. This is not possible on the VP1000 [Wu 2003]. Also, memory requirements, complexity and performance on current graphics processors leads us to look for alternative solutions to displaying multiple activation areas. e-mail: jch@terarecon.com Image rendered the TeraRecon VolumePro 1000.
