This invention, designates that it indicates in accurately the part where image pickup it has done is suitable to some region of the patient with the endoscope without using the special endoscope anew, as purpose. As for operation support information display device 1, being positioned in endoscope, 11 and endoscope 11 the sign sphere the CT device due to the surface form calculation section calculating the coordinate of sign sphere 12 from the axis of coordinates agreement section 44 which matches the form of the patient surface which was calculated from form and the picture of the patient surface 43 which calculates the information which from the image pickup device 20 which image pickup it does the surface and sign sphere 12 of 30 which acquires the information which shows the form of 12 which is locked and patient 60 and patient 60 and the picture shows the form of the surface of patient 60 and CT device 30 and the picture, image pickup direction of endoscope 11The endoscope optical axis calculation section the intersection calculation section it has with the output section 47 which being superimposed, outputs the information which shows the intersection in the information which shows the form of 46 which calculates 45 which calculates the half line which shows the optical axis and the half line and the intersection of the surface which forms inside patient 60 and patient 60.本発明は、新たに特殊な内視鏡を用いることなく、内視鏡で撮像している部分が患者のどの部位に相当するかを正確に表示することを目的とする。手術支援情報表示装置1は、内視鏡11と、内視鏡11に位置決めされて固定される標識球12と、患者60の形状を示す情報を取得するCT装置30と、患者60の表面及び標識球12を撮像する撮像装置20と、画像から患者60の表面の形状を示す情報を算出する表面形状算出部43と、CT装置30による患者表面の形状と画像から算出された患者表面の形状とをマッチングする座標軸一致部44と、画像から標識球12の座標を算出して内視鏡11の撮像方向の光軸を示す半直線を算出する内視鏡光軸算出部45と、半直線と患者60内部を構成する面との交点を算出する交点算出部46と、患者60の形状を示す情報に交点を示す情報を重畳して出力する出力部47とを備える。
