Evaluation of a marker-less, intra-operative, augmented reality guidance system for robot-assisted laparoscopic radical prostatectomy.

abstract：PURPOSE:Most software systems for oral implantology are based on a two-dimensional multi-view approach, often accompanied with a surface rendered model. Usually they are affected by common errors like anisotropy of the volume and distortion on measurements. A more integrated and realistic 3D approach for implant surger...
