【摘要】 介绍一种高能旋转物体CT(HeroCT)随机投影的角度识别研究。采用ns和μs闪光X射线,对高能旋转物体进行透射可以获取一系列瞬时投影。在闪光无法与旋转物体角移严格同步时,为进行CT图像重建,需对这些随机投影的投影角进行识别和确定其在正弦图上的位置。利用计算机模拟,对投影角识别方法进行了研究。更多还原

【Abstract】 An angle identification method for random projections of highenergyrotatingobject CT (HeroCT) is presented. By using nanosecond or microsecond flash Xray, a series of instant projections transmitting a highenergyrotatingobject can be obtained. In case of no way to make synchronizing between the flash and the rotating, one has to identify the angle of all the random projections on the Sinogram before doing CT image reconstruction. A computer simulation for angle identification is described.更多还原
