✦ Synopsis

Abstract

Stereoscopic MRI can impart 3D perception with only two image acquisitions. This economy over standard multiplanar 3D volume renderings allows faster frame rates, which are needed for real‐time imaging applications. Real‐time 3D perception may enhance the appreciation of complex anatomical structures, and may improve hand‐eye coordination while manipulating a medical device during an image‐guided interventional procedure. To this goal, a system is being developed to acquire and display stereoscopic MR images in real‐time. A clinically used, fast gradient‐recalled echo‐train sequence has been modified to produce stereo image pairs. Features have been added for depth cueing, view sharing, and bulk signal suppression. A workstation was attached to a clinical MR scanner for fast data extraction, image reconstruction and stereoscopic image display. Magn Reson Med 46:317–323, 2001. Published 2001 Wiley‐Liss, Inc.
