Research: Auditory Display for Liver Surgery

Image-guided surgery methods for liver resection are gaining popularity because they allows surgeons to view anatomical structures and planning data on a screen in the operating room as well as view the real- time position of a surgical instrument on a 3D model of the liver.

However, the surgeon must frequently switch between viewing the patient and the computer screen and is often not aware of the presence of anatomical risk areas which may be located near the instrument. This thesis presents an auditory display that addresses these two limitations. The auditory display extends the image-guided surgery system by helping guide the surgeon to keep the instrument on the desired resection surface and notifying the surgeon when the instrument approaches nearby risk structures.

Results from evaluations of the auditory display with surgeons and surgical assistants confirm that the system is a beneficial addition to image-guided surgery that reduces the dependence of the surgeon on the visual display and increases awareness of risk areas.
