Abstract
A high resolution detector having a scintillation crystal for receiving incident X-rays at a front face and interacting with the radiation to generate corresponding visible light radiation. Silicon photodiode arrays are positioned on top and bottom lateral faces of the scintillation crystal to receive the visible light that is radiated laterally with respect to the direction of propagation of the incident X-rays. Photodiode elements in each photodiode array extend from the forward face of the scintillation crystal in the direction of propagation of the incident X-rays. The length of the photodiode elements determines the radiation stopping power of the high resolution detector and the height of the front face of the scintillation crystal determines the resolution of the detector. The height of the forward face of the crystal may be made small with respect to the length of the photodiode elements to provide a detector having high resolution and high radiation stopping power.
