Investigation of patient release examination training in nuclear medicine using mixed reality

Abstract

In nuclear medicine, assessing residual radioactivity before patient release is essential. It is typically assessed by radiation detection with a survey meter. This protocol inadvertently exposes to radiation and requires proficiency in the use of the survey meter. This study developed a mixed reality system designed to provide exposure-free training during patient release examination. This system involves a virtual radiation source with visualized radiation emission on the corresponding part of the human mannequin. The time response characteristics of the survey meter to changes with the time constant in addition to the source distance were simulated in realtime.
