We describe a new emission tomographic technique, using an Anger scintillation camera and a new family of coded apertures, in which a noniterative computer algorithm is used to reconstruct multiplanar images. The novel feature is a set of spatial narrow band filters that allow the depth information to be separated in the frequency domain. The position of the reconstructed planes can be selected at will. Using this technique, a planar resolution of 0.75 cm and a depth resolution of 1.6 cm have been measured at a depth of 10 cm and a magnification of 1. To demonstrate the potential of this system, the results of a phantom study are reported.
我们描述了一种新的发射断层扫描技术，该技术使用安格闪烁相机和一族新的编码孔径，其中采用非迭代计算机算法重建多平面图像。其新颖之处在于一组空间窄带滤波器，可在频域中分离深度信息。重建平面的位置可随意选择。利用该技术，在10厘米深度和1倍放大率下测得平面分辨率为0.75厘米，深度分辨率为1.6厘米。为证明该系统的潜力，报告了一项体模研究的结果。
