PURPOSE:To improve operability by providing a first means to set a visual flat plane at a desired position in the inside of an object and a second means to obtain a projecting image at the visual plane in the inside of the object by tracing a beam of light from a preset visual flat plane. CONSTITUTION:The first means 10 to set the visual flat plane 18 at the desired position in the inside of the object, and the second means 12 to obtain the projecting image 20 at the visual flat plane in the inside of the object by tracing the beam of light from the preset visual flat plane 18 are provided. Thereby, since the change of three-dimensional image data of boxer structure, that is, clearing of data in the trace of the beam of light to obtain a surface image in the inside of the object is not required, it is possible to respond to the re-setting of the visual flat plane due to excessive cutting in a conventional case easily, thereby, the operability can be improved. |
