| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently we developed a novel SPECT image reconstruction method that includes attenuation compensation (AC), collimator-detector response compensation (CDRC) and Monte Carlo-based scatter compensation (MCSC). The aim of this study was to quantitatively evaluate our reconstruction method for brain SPECT by phantom experiments with Tc-99m. We performed the following experiments using a SPECT camera with LEHR parallel-hole collimator (GCA-7200A, Toshiba, Japan): (1) measurement of spatial resolution with line sources, (2) evaluation of quantitaion with pyramid phantom, eccentric ring phantom, 2D brain phantom and 3D phantom. These results suggested that our reconstruction algorithm with AC, MCSC and CDRC was valid to improve resolution and quantitation in brain SPECT. | |
