We present an automatic and accurate technique for 3D co-registration of SPECT and CT. The method will allow for attenuation correction of SPECT images and fusion of the anatomic details from CT and the functional information from SPECT. Registration was achieved by optimizing the mutual information metric over the parameter space defined by the translation and rotation parameters. To improve the robustness and accuracy of the algorithm, registration was performed in a coarse-to-fine manner. Wedoi:10.1109/isspit.2006.270781 fatcat:tyjxbis5lneiznt2fcjyhcoqya
