The Neuro-ECAT scanner is a positron emission tomograph designed for high resolution cross-sectional imaging of the adult human head, or the complete torso of a child or small animal. The Neuro-ECAT scanner performs both rectilinear and tomographic scans, in both transmission and emission modes. There are three detector planes, producing five images. Each(More)
The design and performance characteristics of ECAT-II, a second generation whole-body positron imaging system, providing high contrast, high resolution, quantitative images in two-dimensional and tomographic formats is presented. Discussed are: (i) a description of ECAT-II; (ii) the design criteria and implementation for maximizing image quality by(More)
A new system (NEUROECAT) has been designed and built for quantitative positron emission computed tomography (PCT) of the brain. It consists of three octagonal arrays of bismuth germanate detectors (BGO) providing 5 simultaneous image planes. The design utilizes unique shielding and detector geometries which optimize uniformity in image and axial resolution(More)
