抄録
内容記述 近年,確率共鳴と呼ばれる現象が非線形システム内で発見され,これを応用する研究が様々な分野で行われるようになってきた.そこで本研究では,X線CT画像において確率共鳴が発現するのかどうかについて検討した.その結果,白色ノイズの付加によって,確率共鳴現象がCT画像上で発現することがわかった.さらに、コントラストと付加ノイズとの関係において,コントラスト分解能を最大にするノイズ強度の存在も明らかとなった.Recently, phenomenon called Stochastic Resonance was found in a nonlinear system, and has been applied for many researches in various fields. In this study, we have verified that Stochastic Resonance appeared in CT images by adding white-Gaussian noise to CT images. Furthermore, we have also evaluated relationship between contrast and noise intensity added to CT images, and found the suitable noise intensity which maximizes the contrast resolution in CT images.
