Modified Gaussian Interpolations with Geometric Calibrations for Rapid Constructions of Circular-Orbit Pinhole SPECT System Matrices

For high-spatial-resolution reconstructions in SPECT imaging, an accurate and fine system matrix ( H matrix) should be constructed. In this study, the modified Gaussian interpolation method (GIM) and the modified GIM combined with geometric parameter estimations (GIMGPE) are developed to rapidly con...
