Title:
【発明の名称】放射線検出器
Document Type and Number:
Japanese Patent JP2941306
Kind Code:
B2
Abstract:
PURPOSE:To prevent crosstalk as caused by leakage of light to a photo detector at an adjacent channel by providing a second reflecting member at least one end of scintillator elements in a direction orthogonal to the way of arranging the elements side by side along the collateral direction thereof. CONSTITUTION:Spacers 2 and scintillator elements 1 are arranged alternately side by side and a spacer 9 as second reflecting member is inserted into a groove 20 provided at an end thereof in a direction of slicing the elements to join using an adhesive. The scintillator elements 3 thus inserted and joined are bonded together with a transparent adhesive on a printed wiring board 7 on which a multi-channel type photo diode 5 is mounted in such a manner that channels match the elements 1. Then, incident X rays are inputted into the elements 1 through a collimator 11 in a range of an end face (b) from an end face (a) of a slit 10 for shielding scattered rays. As the spacer 9 is arranged on an outer surface from the extension of an X-ray incident surface of the slit 10, out of light emitted with the elements 1, light in a slicing direction is absorbed by the spacer 9. This eliminates leakage of light between the elements 1 thereby allowing the prevention of crosstalk.
