Detector module unit, radiation detector and x-ray computer tomography apparatus

Abstract

To efficiently cool a signal processing circuit.SOLUTION: A detector module unit according to an embodiment includes a detecting element array, a signal processing circuit, a holding plate, and a housing. The detecting element array has a plurality of detecting element for converting a radiation ray into an electric signal arranged therein. The signal processing circuit processes the electric signal. The holding plate holds the detecting element array and the signal processing circuit. The housing has a first surface and a second surface opposed to each other through the holding plate and is thermally connected with the signal processing circuit. The first surface and the second surface of the housing has fins, respectively.SELECTED DRAWING: Figure 5B
