Augmented reality: 3D image-guided surgery
Background Over the last three decades, surgical practice has undergone a significant change with a move towards minimally invasive surgery (MIS) as the standard of care [1]. Although this has brought with it significant benefits, problems have also been associated with the advent of MIS. Perhaps the most substantial limitation associated with MIS is the loss of haptic feedback; this deficit is...
متن کاملMedical Augmented Reality based on Commercial Image Guided Surgery
Utilizing augmented reality for applications in medicine has been a topic of intense research for several years. A number of challenging tasks need to be addressed when designing a medical AR system. These include the import and management of medical datasets and preoperatively created planning data, the registration of the patient with respect to a global coordinate system, and accurate tracki...
متن کاملAugmented Reality in Laparoscopic Surgery
A trend in abdominal surgery is the transition from open procedures to minimally invasive laparoscopic interventions, where visual feedback to surgical staff is only available through the laparoscope camera and direct palpation of organs is impossible. To successfully perform such sophisticated interventions, the provision of additional intraoperative feedback can be of great help to the surgic...
متن کاملAugmented Reality Visualization for Laparoscopic Surgery
We present the design and a prototype implementation of a three-dimensional visualization system to assist with laparoscopic surgical procedures. The system uses 3D visualization, depth extraction from laparoscopic images, and six degree-of-freedom head and laparoscope tracking to display a merged real and synthetic image in the surgeon’s video-see-through head-mounted display. We also introduc...
متن کاملModeling Augmented Reality System, Image Guided Surgery Case Study
An Augmented Reality (AR) system supplements the real world with virtual (computer-generated) objects that appear to coexist in the same space as the real world. [2]. The main interactive characteristic that emerges from these systems is the user focus shared between real and virtual worlds. This limitation results in two different interfaces possibly inconsistent – one to deal with the physica...
