Abstract
A subject ( ) is disposed adjacent a detector array ( ) for the purposes of nuclear imaging. The subject ( ) is injected with a radioactive isotope ( ) and &ggr;-ray emissions indicative of nuclear decay are detected at the detector array ( ). P-ASIC ( ) preamplifier circuits are complex low-noise integrated circuits which dissipate a considerable amount of power (300-500 mW each). These components account for most of the dissipated power on the daughter cards ( ). In order to facilitate the cooling of these electrical components, they are mounted on circuit boards ( ) that are arranged parallel to each other extending perpendicularly away from the detector array ( ). This provides channels between the boards through which cooling air is drawn by an array of fans ( ).
