ABSTRACT:
In a CT imaging system which includes a gantry having a rotatable ring member and a DAS comprising circuit boards grouped in a selected number of sets, a DAS housing is provided which is disposed to dissipate heat away from the DAS circuit boards. The housing includes a frame for mounting each of the circuit boards on the gantry ring so that the boards of a set are in spaced-apart relationship with each other, and further includes a cover for each frame, to form an enclosure for the circuit boards supported thereby. Each cover is provided with a panel member, a section of each panel being provided with a specified pattern of perforations. Each panel is positioned with respect to its set of circuit boards to provide an unobstructed space of selected dimension between its pattern of perforations and its corresponding circuit board set.
