摘要
Computerized method and system for improving 3D reconstruction imagesinvolves applying the Extended Field Iterative Reconstruction Technique(EFIRT)to remove correlated noise, in addition to with COMET (constrained maximumrelative entropy tomography) or other regularization techniques to eliminateuncorrelated noise, wherein the EFIRT is applied by performing a set ofsuccessivereconstructions on an extended field larger than a region of interest (ROI);andextracting and averaging the ROI from said set of successive reconstructions.
