Imaging system

摘要

An imaging device includes a support member (30), a x-ray source (32) mounted to the support member via a first arm (34), and an x-ray detector (36) mounted to the support member via a second arm (38). The x-ray detector includes a sealed housing mounted to the second arm and a flat panel image receptor (74) retained within the housing. A cooling system exchanges heated air in the housing with ambient air located remote from the housing. The support member (30) includes an open channel, a closed channel, a common wall separating the open channel from the closed channel, and a series of vents through the common wall. The second arm includes an inlet passage and an exhaust passage each of which communicate with the closed passage and interior cavity of the housing. At least one fan is positioned in at least one of the exhaust passage and the inlet passage. An air deflector extends over the inlet passage and the outlet passage at the first end thereof to prevent exhaust air from being drawn into the inlet passage. A baffle extends through the cavity to direct the flow of air within the cavity. <IMAGE>
