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.
