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.
