Outline of Final Research Achievements

The purpose of this study is to develop an image reconstruction tool that enables us to understand the various characteristics of digital tomosynthesis. In this study, the projection data were generated using the Monte Carlo code PHITS, which can simulate various radiation behaviors in materials. The aim of this study is to create an educational aid that can be used to understand the various characteristics of tomosynthesis in facilities without dedicated equipment by incorporating the image reconstruction algorithm of tomosynthesis. The results of this study suggest that the characteristics of digital tomosynthesis can be understood even in the absence of dedicated equipment by performing pseudo-digital tomosynthesis image reconstruction.

Academic Significance and Societal Importance of the Research Achievements

本ツールを学生教育に適用することによりトモシンセシス専用の装置を所有していない教育施設においても疑似的にデジタルトモシンセシスの画像再構成を体験することができる。さらに実機では変更できない再構成パラメータを任意に変更することができるため、簡易的にデジタルトモシンセシスの諸特性を把握することができ、教育補助ツールとして効果的なものになると期待できる。
