A flexible microdome-grooved Gd(2)O(2)S:Tb scintillator is simulated, fabricated, and characterized for digital radiography applications. According to Monte Carlo simulation results, the dome-grooved structure has a high spatial resolution, which is verified by X-ray image performance of the scintillator. The proposed scintillator has lower X-ray sensitivity than a nonstructured scintillator bu...

Sarah Whiley holds a bachelor’s degree in Electrical Engineering from the University of Cape Town. After completing her MSc in Biomedical Engineering at the same institution, studying anterior-cruciate ligament repair, she spent three years completing a doctorate in the Department of Orthopaedic Engineering at the University of Edinburgh, developing techniques for assessing fracture healing usi...

Rice algorithm, which has been recommended by Consultative Committee for Space Data System (CCSDS) for space telescope image lossless compression, is studied. Due to the similarity, this algorithm is applied on lossless compression of X-ray digital image after improvement and a satisfying compression rate is obtained. Firstly, the algorithm process is presented. Later on, the compression and de...

Stereo x-ray radiography attracts increasing attention in major clinical applications. The purpose of this paper is to analyze the 3D localization error for breast biopsy procedures and provide guidelines for improving its accuracy. Our prototype is a CCD based digital stereo x-ray imaging system. The mathematical model consists of two x-ray sources and one stationary detector plane. A closed f...
