High-resolution digital x-ray imaging with solid state linear detectors

摘要

Abstract: Solid state x-ray detectors produce high resolution medical images when scanning the patient with a narrow x-ray beam. The x- ray detection is achieved by a silicon photodiode array coated by a scintillating material. Signal is multiplexed and converted into a 12-bit coded digital signal. This technology provides several key advantages for imaging systems: very wide image dynamic range, high resolution, good linearity, no geometrical distortion. The output signal is digital and can be directly acquired by digital processing systems. Major performance in medical imaging applications is given. They fit the requirements of medical systems in several applications fields. The application in panoramic dental x-ray imaging is briefly described. !0
