我们报告的三维光声计算机断层扫描重建算法的结果。一个通用的反投影公式，提出了三种类型的成像几何形状：平面，球面和圆柱表面。在反投影公式中引入了立体角加权因子，以补偿探测视角的变化。描述了实现该算法的方法。数值仿真验证了算法的性能。
We report results of a reconstruction algorithm for three-dimensional photoacoustic computed tomography. A universal back-projection formula is presented for three types of imaging geometries: planar, spherical, and cylindrical surfaces. A solid-angle weighting factor is introduced in the back-projection formula to compensate for the variations of detection views. A method for implementing this algorithm is described. Numerical simulation is used to demonstrate the performance of the algorithm.
