Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming X-ray radiation into visible light that can t...
改进后Ray-Box Intersection权系数矩阵的SART+TVM重建算法
联合代数重建 全变差最小化 Ray-BoxIntersection算法 双线性插值算法 权系数矩阵
2016/7/28
针对均匀采样稀疏型重建问题，研究了Ray-Box Intersection和传统的双线性插值两种权系数矩阵计算方法。对Ray-Box Intersection算法的逻辑漏洞进行了改进，利用直线生成法并结合射线斜率和像素位置关系提出了改进算法。该算法利用代数关系求得射线穿过重建区域的起点和终点，然后取不大于其坐标的最大整数，最后采用直线生成法，依据射线斜率沿X或Y方向得到该条射线在投影区域内经过的所...
