超音波診断支援システムのための3次元追従ビジュアルフィードバック系の構築

抄録

Among various medical problems facing us in today's Japan are rapidly aging society, localization of medical doctors, concentrated visits of patients to large hospitals, etc. We have developed an ultrasound diagnosis and treatment support system for reducing the burden of doctor and patient so far. We succeeded in the tracking of the organ which moved a dislocation image by body movement or breathing. However, the conventional ultrasound probes, for tracking the three-dimensional movement of the organ has been difficult. In this paper, we performed experiments using gallbladder by echogram processing software and measured the distance of organ. As a result, we determined the index of visual feedback to track the center of the gallbladder always. Next, we improved the image processing system so as to change the region of interest of echogram. Based on this feature amount, we discussed about the three-dimensional movement of an organ.
