Abstract: In this study, we evaluated a new method for registering three-dimensional ultrasound (3DUS) data to external coordinate systems. First, 3DUS was registered to the stereo endoscope of a da Vinci Surgical System by placing a registration tool against an air–tissue boundary so that the 3DUS could image ultrasound fiducials while the stereo endoscope could image camera markers on the same tool. The common points were used to solve the registration between the 3DUS and camera coordinate systems. The target registration error (TRE) when imaging through a polyvinyl chloride (PVC) tissue phantom ranged from to using one to four registration tool positions. TRE when imaging through an ex vivo liver tissue sample ranged from to using one to four registration tool positions. Second, using a similar method, 3DUS was registered to the kinematic coordinate …
