Radiation detecting element

摘要

Provided is a radiation detecting element, including: needle crystal scintillators and a protruding pattern in which: one end of the needle crystal scintillators is in contact with of upper surfaces of the multiple protrusions; a gap corresponding to a gap between the multiple protrusions is provided between portions of the needle crystal scintillators in contact with the upper surfaces of the multiple protrusions; and a number of the needle crystal scintillators in contact with one of the upper surfaces is 5 or less. Conventionally, since the needle crystals exhibit a state of a polycrystalline film in an early stage of vapor deposition, and light also spreads in a horizontal direction, the light received by a photodetector portion and the spatial resolution was lower than ideal values. The present invention enables the deviating region to be the ideal state in an early stage of growth.

1. A radiation detector comprising:
multiple pixels, wherein each of said multiple pixels is a radiation detecting element comprising:
needle crystal scintillators;a protruding pattern layer including multiple protrusions, each having a surface, with a gap between them; anda photodetector configured to detect scintillation light emitted by said needle crystal scintillators, wherein:one end of said needle crystal scintillators is in contact with the surfaces of said multiple protrusions;a gap corresponding to the gap between said multiple protrusions is provided between portions of said needle crystal scintillators where said needle crystal scintillators are in contact with said surfaces of said multiple protrusions; andthe number of said needle crystal scintillators which are in contact with the surface of one of said multiple protrusions is 5 or less, andwherein at least two of said multiple protrusions are arranged on one of said photo detectors.
