The invention relates to a medical device which relates to the detector CT, ct. It includes the main substrate (1) and a plurality of detection unit (2), each detection unit (2) including crystal (21) and a photodiode (22), photodiode (22) receiving surface (23) and crystal (21) combined with the one side, the detection unit (2) the direction of the same, and the photodiode (22) receiving surface (23) parallel to the X-ray direction is fixed on the main substrate (1). The use of CT? Detector can improve the intensity of X-ray and does not change the signal pixels smaller, received other structure in the case of a stronger signal, the pixel size is half of the detector, the receiving efficiency is higher, is 100 times the current detector, photoelectric receiving area two transistor to expand more than 20 times. A signal detected by the detector unit detects the size and the smaller, higher signal-to-noise ratio, better image quality of CT.
