Augmented reality: 3D image-guided surgery

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...

Modeling 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...

Medical 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...

Augmented Reality Enhanced Image-Guided Surgery System Using CT and Ultrasound Registration for Brain-Shift Estimation

In neurosurgery, brain shift, usually caused by the gravity or the changes of intra-cranial pressure, is the main factor to affect the accuracy of tumor removal. To deal with this problem, an imageguided surgery system which corrects the brain shift from the preoperative CT images by using intra-operative ultrasound images is presented. First, with reconstructing 2-D free-hand ultrasound images...
