プローブ走査手技データベースに基づく超音波検査教育システムの構築

抄録

Echography has advantages of small size, inexpensive, and low invasiveness. However, it requires proficiency in probe scanning to obtain desired echogram. Therefore, training equipment and simulated human bodies for echography education have been released, but there have been few case databases of patients. Therefore, in this study, we developed an ultrasound training system, ECOT. In this paper, we constructed a coordinate transformation system that correctly measures probe posture and a matching system that adds time information to the position and posture information to improve the matching accuracy of ECOT. As a result, we succeeded in obtaining the position and posture of the probe tip independent of the type and position of the measurement system. Even when the database was constructed from organs whose shape changes over time, we were able to construct a system that displays echographic images in the same way as the real body by adding time information.
