Abstract

An X-ray CT detector is disclosed which detects the intensity of X-rays emitted from an X-ray source and transmitted through a subject. The detector comprises a multi-channel scintillator element array and a multi-channel photo-semiconductor element array. The scintillator element array and photo-semiconductor element array are bonded together in an arcular form. The scintillator element array consists of a plurality of polycrystalline pieces each constituting a scintillator element which emits light according to X-ray incidence. The photo-semiconductor element array is provided on the outer side of the scintillator element array and consists of an amorphous silicon film. The photo-semiconductor element array has a plurality of photo-semiconductor element sections each corresponding to each scintillator element and detecting the intensity of light emitted from each scintillator element.

Dependent claims

A detector for detecting the intensity of X-rays emitted from an X-ray source and transmitted through a subject to said detector, said detector comprising:

an arcular multi-channel scintillator element array having a plurality of polycrystalline pieces, each of said polycrystalline pieces constituting a scintillator element which emits light in accordance with X-ray incidence, said polycrystalline pieces being positioned adjacent to one another to form a receiving surface for receiving the X-rays and to form an outer surface opposite said receiving surface;
and
a multi-channel photo-semiconductor element array provided on said outer surface of said multi-channel scintillator element array, said photo-semiconductor element array including a plurality of photo-semiconductor element sections having an amorphous silicon film formed on a flexible insulating film, each of said photo-semiconductor element sections detecting the intensity of light emitted from a corresponding one of said scintillator elements.
