PROBLEM TO BE SOLVED: To make sufficiently accurately detectable the movement of an organ or a curative range by defining the point or the part of an organ or a curative range moved in an image, determining the course caused by the movement, and obtaining the characteristic point to the moving course to be displayed together with the position of an image plane. SOLUTION: When the liver 2 of a patient 1 has a lesion to be cured, a sensor 4 is fitted to the surface of a patient 1, and the positions of them are detected by a navigation system 5. A supersonic image of the liver 2 is imaged by an ultrasonic applicator 6 of an ultrasonic image pickup system 7, and the image data are applied to a center computing device 8 to be output in the form of an ultrasonic image to a monitor 9. In order to detect the movement of the liver 2 inside the coordinate system and display the same, a point P in an organ, for example, a lower edge of the liver is selected by the monitor 9, the movement of the point P is traced and the movement course is determined by the computing device 8. The display of the course is made by another monitor 10 where the coordinate system where the movement path is detected is displayed. |
