摘要
PROBLEM TO BE SOLVED: To provide a prosthetic artificial bone design system and the production of prosthetic artificial bone with which the form of a lacked part can be more exactly grasped and the shape accuracy of an artificial bone to be provided or accuracy of matching to the lacked part can be improved as a result. SOLUTION: In respective tomographic images 90 photographed at mutually different plural tomographic positions, the pixel area of a predetermined density level is extracted as a one candidate area 108. Then, (determined bone areas) 93 and 110 to be finally used as bone areas are selected out of the bone candidate area 108 and on the basis of these determined bone areas 93 and 110, bone outline information 103 is generated as the outline information on the area to be finally determined as a bone part. On the basis of the bone outline information 103 for each tomographic position, three-dimensional(3D) shape data showing the lacked part of the bone part are prepared and while referring to these 3D shape data, a material to be worked is worked into prosthetic artificial bone shape.
