DIY navigation system for surgeons

Maki Sugimoto
Apple brings a story of professor Maki Sugimoto of Teikyo University Chiba Medical Center, a gastrointestinal surgeon, who wanted a better approach to navigation for planning and performing both aggressive and minimally invasive surgeries. He uses Apple computers with OsiriX imaging software to project 3D images onto a patient’s abdomen for both laparoscopic and midline open surgery.

Laparoscopic surgery

For patients with early-stage gastric or colonic cancer, the surgical team typically opts for minimally invasive laparoscopic surgery. With the patient anesthetized, Sugimoto projects OsiriX-generated 3D images onto the body surface of the patient with an Epson EMP-1715 projector. Using a motion-sensing wireless remote, Sugimoto uses physiological markers (such as the navel) to register the image to the patient’s body. Then using a Color Look Up Table (CLUT) feature in OsiriX, he makes the skin of the image transparent. The display now shows the patient’s internal body parts and the area that he will need to operate on.

Open surgery

“The 3D visualization shows us relationships between the cancer and the arterial vessels and other surrounding organs,” says Sugimoto. “It also allows us to see the extent of the spread of cancer. When a patient has upper biliary (bile duct) cancer, we have to cut the liver. If the patient has lower bile duct cancer we have to remove the pancreatic head and duodenum. The HBP system is very complex; that’s why 3D visualization in the OR is so crucial. When doing a midline open surgery, the surgeon can only see the organs from the top. With OsiriX on the Mac, surgeons can rotate and see the surrounding organs in 3D to guide them during surgery.
