| 摘要 |
The invention concerns a display device (10) for implementing a method comprising an echographic probe (11), preferably a cylindrical probe, and two video-film cameras (12, 13), whereof the first (12) is arranged substantially perpendicular relative to a working plane (14) defining a working zone wherein the internal anatomical anomaly is located and the second (13) is angularly offset relative to the first. The first camera (12) is substantially vertical and reads the co-ordinates XOY of positions sighted at 90 DEG and reads the co-ordinates YOZ of said positions. Said calibrating enables to determine the spatial co-ordinates of the cameras and then calculate the exact positioning of the wave generator of the treating apparatus on said anomaly.
