PURPOSE:To execute an exact simulation for a jawbone and face surgical operation, etc., by allowing a display means to display an image overlap part which follows up a movement of a cutting part by a display state which can be discriminated from the priphery. CONSTITUTION:A cutting processing of a three-dimensional image is executed by an image cutting processing means 7 and a fitting processing of a cutting part which has been cut by said processing is executed by a fitting processing means 13. A result of processing is displayed on a display means 12, and in this state, in case an image overlap part has been generated by following up a movement of the cutting part, this image overlap part is displayed on the display means 12 by a displace state which can be discriminated from the periphery under the control of a display control means 11. In such a way, whether a part in which a movement of the cutting part is difficult exists or not, or whether fitting of the cutting part into a prescribed area can be executed smoothly or not can be discriminated easily. |
