Augmented Reality Visual Guidance for Spatial Perception in the Computer Assisted Surgical Trainer
نویسندگان
چکیده
We propose several augmented reality overlays for visual guidance in training for laparoscopic surgery using a 2D display, with the goal of aiding the user’s perception of depth and space in that limiting environment. A pilot study of 30 subjects (22 male and 8 female) is presented with results showing the effect of the various overlays on subject performance of a path following task in the Computer Assisted Surgical Trainer. Deviation, economy of movement, and completion time are considered as metrics. The use of a reference indicator for the nearest point on the optimal path is found to result in significant reduction (p < 0.05) in some deviation metrics using non-parametric tests of significance. The data also indicate a reduction in subject deviation with overlays designed to provide depth information. Avenues for further investigation are presented.

Augmented Reality Guidance with Multimodality Imaging Data and Depth-Perceived Interaction for Robot-Assisted Surgery
Image-guided surgical procedures are challenged by mono image modality, twodimensional anatomical guidance and non-intuitive human-machine interaction. The introduction of Tablet-based augmented reality (AR) into surgical robots may assist surgeons with overcoming these problems. In this paper, we proposed and developed a robot-assisted surgical system with interactive surgical guidance using t...
متن کاملpq-space Based Non-Photorealistic Rendering for Augmented Reality
The increasing use of robotic assisted minimally invasive surgery (MIS) provides an ideal environment for using Augmented Reality (AR) for performing image guided surgery. Seamless synthesis of AR depends on a number of factors relating to the way in which virtual objects appear and visually interact with a real environment. Traditional overlaid AR approaches generally suffer from a loss of dep...

Radiofrequency (RF) ablation is a good alternative to hepatic resection for treatment of liver tumors. However, accurate needle insertion requires precise hand-eye coordination and is also affected by the difficulty of RF needle navigation. This paper proposes a cooperative surgical robot system, guided by hand gestures and supported by an augmented reality (AR)-based surgical field, for robot-...
متن کاملIntra-operative ultrasound-based augmented reality guidance for laparoscopic surgery
In laparoscopic surgery, the surgeon must operate with a limited field of view and reduced depth perception. This makes spatial understanding of critical structures difficult, such as an endophytic tumour in a partial nephrectomy. Such tumours yield a high complication rate of 47%, and excising them increases the risk of cutting into the kidney's collecting system. To overcome these challenges,...
متن کاملTracking of Irregular Graphical Structures for Tissue Deformation Recovery in Minimally Invasive Surgery
Tissue deformation tracking is an important topic of minimally invasive surgery with applications ranging from intra-operative guidance to augmented reality visualisation. In this paper, we present a technique for visual tracking of irregular structures with an arbitrary degree of connectivity in space. The variational formulation of the proposed method ensures that correlation is maximised bet...
