Tissue Structure Updating for In Situ Augmented Reality Navigation using Calibrated Ultrasound and Two-level Surface Warping 170 177 IEEE Transactions on Biomedical Engineering (TBME)
In minimally invasive surgery, in situ augmented reality (AR) navigation systems are usually implemented using a glasses-free 3D display to represent the preoperative tissue structure. However, due to changes in intraoperative tissue, the preoperative tissue structure is not able to exactly correspond to reality. To solve this problem, we propose a method to update the tissue structure for in situ AR navigation in such way to reflect changes in intraoperative tissue. Experiments confirm that the novel AR navigation system based on updating the tissue structure will open up a better approach to provide accurate 3D see-through guidance. read more

Simultaneous Optimization of Patient–Image Registration and Hand–Eye Calibration for Accurate Augmented Reality in Surgery 170 177 IEEE Transactions on Biomedical Engineering (TBME)
For augmented reality (AR)-guided endoscopic surgery, patient–image registration and hand–eye calibration are essential steps and they have been separately performed so far with accumulating errors. In the proposed method, the two separate steps are integrated in a single step with minimized errors under the on-site AR condition. The AR superimposing accuracy can increase due to the reduced computational complexity of transformation processes and the compensated tracking errors of the position sensor… read more
