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 tracing of the organ which moved a dislocation image by body movement or breathing. However, the ordinary ultrasound probes, for tracing the three-dimensional movement of the organ has been difficult. Therefore, compensation for body movement has been needed. In this paper, we performed experiments using gallbladder by echogram processing software and measured the distance the center of the organ for proposal of visual feedforward control system.
