Abstract
We have developed a Compton camera with a double-sided silicon strip detector (DSSD) for hard X-ray and gamma-ray observation. Using a DSSD as a scatter detector of the Compton camera, we achieved high angular resolution of 3.4° at 511 keV. Through the imaging of various samples such as two-dimentional array sources and a diffuse source, the wide field-of-view (~ 100°) and the high spatial resolution (at least 20 mm at a distance of 60 mm from the DSSD) of the camera were confirmed. Furthermore, using the List-Mode Maximum-Likelihood Expectation-Maximization method, the camera can resolve an interval of 3 mm at a distance of 30 mm from the DSSD.
