RADIATION DETECTING APPARATUS AND RADIATION TOMOGRAPHIC IMAGING APPARATUS

摘要

A radiation detecting apparatus is provided. The radiation detecting apparatus includes a plurality of detector modules arranged in a channel direction, each detector module including a plurality of detecting elements arranged in matrix form in the channel direction and a slice direction, and a heat radiating unit thermally coupled to the detecting elements and provided on an X-ray outgoing side of the detecting elements, a wind blowing unit configured to send wind to the heat radiating units of the detector modules in the slice direction, first wind shielding portions provided on a radiation outgoing side of the heat radiating units and configured to shield the wind in a radiation irradiating direction, and second wind shielding portions provided on a radiation incoming side of the heat radiating units and configured to shield the wind in the radiation irradiating direction.
