Outline of Final Research Achievements

The aim of this study was to develop the high definition technique for the dopamine transporter (DAT) imaging. Since the degradation of a DAT image by the high-energy gamma ray is expressed as a mathematical equation, the effect of high-energy gamma ray can be estimated using this equation. The striatal phantom imaging was performed using the low-energy general-all-purpose (LEGAP) and Fan-beam collimators, and imaging characteristics for two collimators was determined. Moreover, we performed simulation study using a digital phantom and Monte Carlo simulation code.
