Scatter correction in SPECT quantification is of major importance to compensation for the scatter contribution under photopeak. The triple energy windows method (TEW) one suggested ways that are widely used clinical routine. However, it can be a source additional noise if width or number sub-energy not accurately chosen. To determine precise estimation settings 99m Tc photopeak, fraction was ca...

A numerical particle simulation code package to estimate the irradiation distribution of an electron beam machine is presented. Particle-to-particle interactions are calculated using particle-in-cell method, while equation motion solved Boris algorithm. The amplitude oscillating magnetic field from scanning horn obtained CST solver. was run Intel’s i7-10700 processor without multithreading. For...
