Basic evaluation of three-dimensional position sensitive CdTe detector unit for clinical use of ultra-high resolution human PET scanner

We develop ultra-high resolution human PET scanner with the world's first resolution of less than 1 mm, which is used CdTe type semiconductor detectors. The aim of this study is that we develop three-dimensional position sensitive CdTe detector units which construct PET scanner, and evaluate basic performance of this scanner. Here we report about progress and outcome of its development.
