High-resolution autostereoscopic surgical display

This paper proposes a high-resolution stereoscopic surgical display using the integral videography (IV) and multiple projectors. IV projects a computer generated graphical object by multiple rays through "fly's eye lens", which can display geometrically accurate autostereoscopic images and reproduce motion parallax in three-dimensional (3-D) space. This technique requires neither special glasses nor sensing device to track viewer's eyes, thus being suitable for preoperative diagnosis and intraoperative use. This paper reports the use of multiple reduction projection display system and a parallel-calculation to achieve high-resolution IV image. We evaluate the feasibility of this display by developing a 3-D CT stereoscopic image and applying it to surgical planning and intraoperative guidance. The main contribution of this paper is application and modification of medical stereoscopic technique originally developed in high-resolution multi-projector stereoscopic display system.
