Visualization and three-dimensional image processing of positron emission tomography (PET) brain images
Nahum D. Gershon · IEEE Visualization · 1990
The author applied image processing and volume rendering algorithms together with considerations on the physiology of the human visual system to improve the quality of perception of the information contained in positron emission tomography (PET) brain images, and to highlight the existing anatomical information. The psychophysical considerations for selecting color and brightness level are used to visualize functional and anatomical structures in three dimensions. One is able to perceive in the images the levels of rates of glucose metabolism of regions in the brain and their relative locations. In addition, some of the anatomic structures, such as the interhemispheric fissure, the caudate nucleus, and the thalamus, are apparent. >
