摘　　要：A gamma-ray Computed Tomography （CT）technique based on MATLAB has been developed,and its potential for the application of multiphase flow detection has been demonstrated with simulation results.Aiming to improve the real time performance,we design a CT system with fixed sources and limited detecors.By dissecting the imaging region with Delaunay triangulation method,the algebraic reconstruction algorithm and simultaneous multiplicative algebraic reconstruction algorithm re implemented respective algebraic reconstruction algorithm are implemented respectively to reconstruct cross-sectional images.The resultant images can be utilized to identify flow regimes or extract characteristic parameters.
