An algorithm for the digital reconstruction of the Fresnel-coded gamma camera image consists of the spatial Fourier transform of the hologram after applying a quadratic phase shift. Background subtraction is implemented by use of positive and negative zone plates. Tomographic planes are reconstructed in 27 sec from a single zone-plate shadow image by successively varying a parameter in the reconstruction algorithm on a small computer system.
一种用于菲涅耳编码伽马相机图像数字重建的算法，包括在应用二次相移后对全息图进行空间傅里叶变换。背景减法通过使用正、负波带片来实现。通过在小型计算机系统上连续改变重建算法中的一个参数，可在27秒内从单个波带片阴影图像重建断层平面。
