High-Quality 3D Autostereoscopic Medical Display Method with Optical Enhancement and Image Compensation

摘要

With the growing demand for intuitive and accurate medical image visualization, autostereoscopic 3D display becomes a new developing trend in image guided diagnosis and therapy. However, the limited resolution and inadequate accuracy of current autostereoscopic techniques are two common problems that restrict the application of 3D medical display. This research introduces an image enhancement and optical compensation method based high quality autostereoscopic medical display system. An image enhancement module is designed to improve the spatial resolution and viewing angle of the same time. The accuracy degradation caused by optical aberration is compensated by the proposed raytracing rendering. Experiments demonstrated the feasibility in the improvement of 3D image quality and accuracy. Anatomic details of volunteer data were well shown by the proposed method. With further improvements in real-time image rendering, the proposed methods will have wide applicability in improving the display performance in the field of AR guidance system, microscope and head-mounted display systems.
