Computed tomography guided laparoscopy: Proof of concept

Current generation minimally invasive surgeries present many visualization challenges, including two-dimensional representation of three-dimensional anatomy and a lack of visualization of deeply recessed structures. Coupled with the loss of tactile feedback which places greater emphasis on available visual cues, improved surgical visualization remains a long-standing need. Our response to address this need is Live Augmented Reality (Live AR), in which processed images from live radiologie scans of the surgical field are merged with optical images, accounting for spatial and temporal registration. We have demonstrated the feasibility of Live AR, but its clinical implementation is hampered by many current technical limitations. Ln this report, we have presented guidance of a simple laparoscopic maneuver completely based on computed tomography (CT) scanning and rapid 3D rendering of the acquired images in the CT room. The capability developed here and the reported results constitute a step toward the eventual goal of routine clinical implementation of Live AR.
