“…While the software already exists in a prototypical stage, several further improvements are needed for the system integration and hardware components for the clinical application. Additional advancements need to be considered for a more accurate intra-operative registration, for instance by 2D/3D registration to position the patient [9] or threedimensional reconstruction of stereo-endoscope images to register the organs [10].…”

The paper presents a practical approach to measuring liver motion, both respiratory and laparoscopic, with a tool guided in the operating room. The presented method is based on standard operating room equipment, i.e. rigid laparoscopic cameras and a single incision laparoscopic surgery trocar. The triangulation algorithm is used and stereo correspondence points are marked manually by two independent experts. To calibrate the cameras two perpendicular chessboards, a pinhole camera model and a Tsai algorithm are used. The data set consists of twelve real liver surgery video sequences: ten open surgery and two laparoscopic, gathered from different patients. The setup equipment and methodology are presented. The proposed evaluation method based on both calibration points of the chessboard reconstruction and measurements made by the Polaris Vicra tracking system are used as a reference system. In the analysis stage we focused on two specific goals, measuring respiration and laparoscopic tool guided liver motions. We have presented separate examples for left and right liver lobes. It is possible to reconstruct liver motion using the SILS trocar. Our approach was made without additional position or movement sensors. Diffusion of cameras and laser for distance measurement seems to be less practical for in vivo laparoscopic data, but we do not exclude exploring such sensors in further research.

Building a 3D model of the operating field is the first stage to access the registration of pre-operative surface models in per-operative context. We propose a method to learn the 3D model of the organs observed by a stereoscopic endoscope. This method is general and requires no a priori knowledge of the position of the instruments, whether robotized or manually-controlled, present in the field of view. The result of the learning process allows the removal of the instruments from the surgeon's field of view: "diminished reality". This work prefigures the 3D integration by augmented reality of preoperative organs model (e.g. arteries) in stereoscopic images. Experiments are currently being performed to validate our approach using endoscopic sequences from the da Vinci TM surgical system.
