低線量下におけるフォトンカウンティング型 X 線CTの画質評価

抄録

The purpose of this study is to show superiority of photon - counting when radiation dose is low. In this paper, we captured data by photon - counting and conventional method, and evaluate d degradation by difference method. In the result, degradation of photon - counting is less, and we confirmed superiority of photon - counting.
