| Research Abstract |
The purpose of this study is to develop a small detection apparatus for proton computed tomography. Silicon micro strip detectors (SSD) were used to obtain the proton track. Two sets of the X- and Y-strip detectors were each placed behind and ahead of the object. The residual proton energy was measured by the NaI(Tl) detector. We have measured the energy resolution of the NaI(Tl) detector and the 2D images of simple-shaped objects. It is found that the measurement of the upstream trajectory and the downstream independently is quite useful for spatial resolution of the object.
