Abstract
This study proposes an MR image projection device for assisting incision-place marking task in neurosurgery. The proposed interface aims to enhance the neurosurgeon's spatial perception to assist understanding three-dimensional brain structure. It consists of an adjustable translucent screen with projected MR images, and a link arm with sensors to recognize the surgeon's embodied interaction. The proposed device provides haptic interactions that allow the surgeon to manipulate the depth information and spatial views of the three-dimensional brain structure on the basis of their embodied interaction. We conducted task load evaluation experiment and it is suggested that the physical and temporal demands are reduced by using our proposed device.
