Abstract

We have proposed the visual and haptic interface for the tele-echo system where ultrasound (US) probing can be instructed from a diagnostic to measurement site via network. In the measurement site, the surface of a patient body was captured with a CCD camera and the shape of patient was measured using the triangulation. In the diagnostic site, three dimensional image of a patient was reconstructed and a medical doctor could touch the virtual patient body with a haptic device. The position, orientation and tilt of a US probe was transmitted from the diagnostic to the measurement site with our previous proposed mark, called 'Web-Mark' and the mark was projected on the patient directly. The experimental results demonstrated that the proposed system enables to obtain US images, long axis and apex image in the shorter time as compared with the system using two dimensional information of the patient only.
