High-resolution stereoscopic surgical display using parallel integral videography and multi-projector

Abstract

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 pre-operative diagnosis and intra-operative use. This paper reports the use of multiple reduction projection display system and a parallelcalculation 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 intra-operative 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.
