Abstract:
1. A method of cooling a medical imaging system that includes a gantry comprising; supplying air to the gantry; conditioning the supplied air to maintain a predetermined bulk temperature and to facilitate reducing the variation of temperature within the gantry; independently channeling a variable amount of the conditioned air to a plurality of heat producing electronic devices, wherein the heat producing electronic devices are coupled in flow communication with a plurality of fans, wherein at least one of the heat producing electronic devices is coupled within a plenum, wherein at least one of the fans is a plenum fan coupled at an inlet of the plenum coupled within the gantry, and wherein at least one of the fans is an exhaust fan orientated to exhaust the supplied air outside of the gantry; operating a first one of the fans at a speed different than a second one of the fans; detecting local temperatures at at least the heat producing electronic devices and the plenum; and controlling the plenum fan and the exhaust fan based on at least one of the detected local temperatures, the at least one of the detected local temperatures used as a feedback variable to control at least the exhaust fan.
