Cancer is one of the most prevalent and deadly diseases in modern society. The tumor is often made visible through internal imaging such as MRI or CTs. However clear the tumor may be on these images, the task the surgeon faces on the operating table is often a big challenge. Having to rely on sight and feel, he has to locate and remove the complete tumor without leaving any part of it behind, while causing the least possible amount of damage to the surrounding tissues. Since both tumors and organs often have a spongy texture, and things may have shifted since the image was taken, locating the tumor can be very difficult.
This project will look into using projected augmented reality in assisting the surgeon in this task. Before and during the operation structures that are internal to the patient’s body (such as a tumor) will be projected on it. By adjusting the projection based on the location of the surgeon’s head, a “see-through” effect should be obtained, which should allow the surgeon to gain a sense of depth and position, so that it’s possible to see if he’s working in the right direction. Utilizing 3d to enhance the illusion is a possibility.
The system can be expanded for use in other kinds of surgery, and displaying other structures.
