X-RAY DETECTOR HAVING COOLING SPACE

摘要

PURPOSE: An X-ray detector with a cooling space is provided to effective cooling while maximizing the spatial utilization of the detector. CONSTITUTION: An X-ray detector with a cooling space comprises a housing unit (120), a detector panel (110), and a shielding unit (130). The detector panel is arranged in an internal space of the shielding unit to face an X-ray generator and detects X-rays irradiated to a subject. The shielding unit, which is arranged in an internal space of the housing unit, covers the rear surface, a lateral wall, and the front surface of the detector panel for preventing the exposure of radiation to a portion except for a detection region and includes an opening unit for opening the detection region of images on the front surface. The shielding unit is protruded in the front or rear surface of the detector panel and includes a plurality of protrusions in an end portion. The plurality of protrusions supports and fixes the front or rear surface of the detector panel, thereby forming a separate space. Heated air flows in the separate space between the inner periphery of the shielding unit and the detector panel and is discharged to the opening unit.
