Higher resolution has been afforded by the unique focal geometry of the system and greater sensitivity has also been achieved.
About
Summary Researchers at Stanford University have developed a high-performance PET scanner optimized for focal imaging. The scanner uses an optimized, sized, curved, dual-panel configuration that incorporates both photon depth-of-interaction and time-of-flight technologies for a limited angle tomography geometry. This scanner takes advantage of the unique geometry to focus response lines on specific parts of the body to create higher resolution images, with greater sensitivity, but at a lower cost than using a traditional whole body PET scanner.
