An Optimization of Reconstruction Parameters and Investigation Into the Impact of Photon Scatter in ${}^{67}$ Ga SPECT
Abstract
During ${}^{67}$ Ga citrate SPECT imaging, photon downscatter will occur from higher energy photons into lower energy acquisition windows thus possibly adversely affecting reconstructed image quality. With these additional scattered photons present in projection data, the effect of using more complex reconstruction strategies such as three-dimensional detector response compensation (3-D DRC) and attenuation correction (AC) is unclear. Using a …
