Optimized Design of X-ray Spectrum Filter for CT
Abstract：The optimized design of X-ray spectrum filter for computed tomography is studied by Monte Carlomethod in this paper. The generation process of X-ray using electron bombardment metal target and the transportprocess of X-ray through different filters were simulated by EGSnrc software. The formula for optimized designwas presented on the basis of signal to noise ratio （SNR）. The results show that the optimal parameter for filterdesign exists, and it is different under different imaging conditions and requirements, which is determined by theactual conditions.
