TL;DR: A new approach to on-patient visualization of 3D medical images, which combines the concept of augmented reality (AR) with an intuitive interaction scheme is presented, which can be used for intervention planning, anatomy teaching and various other applications that require intuitive visualization of3D data.
3D surface reconstruction for laparoscopic computer-assisted interventions: comparison of state-of-the-art methods
Anja Groch,Alexander Seitel,S. Hempel,S. Hempel,Stefanie Speidel,Rainer Engelbrecht,J. Penne,Kurt Höller,Kurt Höller,Sebastian Röhl,Kwong Yung,Sebastian Bodenstedt,Felix Pflaum,T. R. Dos Santos,Sven Mersmann,Hans-Peter Meinzer,Joachim Hornegger,Lena Maier-Hein +17 more
TL;DR: The evaluation suggests that the ToF technique has high potential as means for intraoperative endoscopic surface registration as well as robust and fast algorithms for establishing correspondences between multiple images of the same scene.
