Correction of solid angle fraction influence on the reconstruction quality in the single photon emission computed tomography

摘要

In single photon emission computed tomography exists scantily explored distorting factor called as solid angle fraction. There is investigated the influence of geometrical attenuation on the reconstruction quality depending on the gabarit of object, the system rotation radius and the absorption coefficient. The iterative method is offered for solid angle fraction distortion correction of the reconstructed image.
