Abstract

Pre-operative CT data is available for several orthopedic and trauma interventions, and is mainly used to identify injuries and plan the surgical procedure. In this work we propose an intuitive augmented reality environment allowing visualization of pre-operative data during the intervention, with an overlay of the optical information from the surgical site. The pre-operative CT volume is first registered to the patient by acquiring a single C-Arm X-ray image and using 3D/2D intensity-based registration. Next, we use an RGBD sensor on the C-Arm to fuse the optical information of the surgical site with patient pre-operative medical data and provide an augmented reality environment. The 3D/2D registration of the pre-and intra-operative data allows us to maintain a correct visualization each time the C-Arm is repositioned or the patient moves. An overall mean target registration error (mTRE) and standard deviation of 5.24 ± 3.09 mm was measured averaged over 19 C-Arm poses. The proposed solution enables the surgeon to visualize pre-operative data overlaid with information from the surgical site (e.g. surgeon's hands, surgical tools, etc.) for any C-Arm pose, and negates issues of line-of-sight and long setup times, which are present in commercially available systems.
