Abstract: According to a method for producing a radiation detection unit, in a first step, a side portion of a first radiation detection module and a first protrusion are abutted. In a second step, a second radiation detection module is arranged within a region from which the first protrusion has been removed, and a side portion of the second radiation detection module and a second protrusion are abutted, after the first step. In a third step, each of the mounting portion of the first radiation detection module and the mounting portion of the second radiation detection module is arranged opposing a frame while spaced apart from the frame, and each of the first radiation detection module and the second radiation detection module is mounted on the frame.

Abstract: A radiation detection module for a CT device that detects radiation includes a detecting section configured to detect radiation, a processing section configured to process a signal from the detecting section, and a heat radiating member thermally coupled to the processing section and configured to dissipate heat generated by the processing section. The heat radiating member has a plurality of fins. The plurality of fins is spaced apart from each other in a first direction along a slice direction of the CT device. Each of the plurality of fins has a plate shape extending so as to intersect the first direction.

Abstract: A connection substrate 13 includes a base material 130 formed by stacking a plurality of dielectric layers 130a to 130f and a plurality of through conductors 20 provided penetrating through the dielectric layers 130c to 130f adjacent to each other. A plurality of radiation shielding films 21a to 23a formed integrally with each of the plurality of through conductors 20 and separated from each other are provided at two or more interlayer parts in the dielectric layers 130c to 130f. A region PR1 of the radiation shielding film 21a (21b) formed integrally with one through conductor 20 in one interlayer part projected onto a virtual plane normal to a predetermined direction and a region of the radiation shielding film 22b or 22c (22c) formed integrally with another through conductor 20 in another interlayer part projected onto the virtual plane do not overlap each other.

Abstract: An object is to prevent occurrence of an insensitive zone to radiation in parallel arrangement of multiple units.

Abstract: A radiation detector module 10A includes a scintillator for converting radiation made incident from a predetermined direction to light, a two-dimensional PD array 12 for receiving light from the scintillator, a connection substrate 13 formed by stacking dielectric layers 130a to 130f, and mounted with the two-dimensional PD array 12 on one substrate surface thereof, and an integrated circuit device 14 mounted on the other substrate surface of the connection substrate 13, and for reading out electrical signals output from the two-dimensional PD array 12. The integrated circuit device 14 has a plurality of unit circuit regions 14b separated from each other. The connection substrate 13 has a plurality of through conductors 20 and a plurality of radiation shielding films 21a to 23a formed integrally with each of the plurality of through conductors 20 and separated from each other.
