Performance Factors In Neurosurgical Simulation And Augmented Reality Image Guidance, Ryan Armstrong
Performance Factors In Neurosurgical Simulation And Augmented Reality Image Guidance, Ryan Armstrong
Electronic Thesis and Dissertation Repository
Virtual reality surgical simulators have seen widespread adoption in an effort to provide safe, cost-effective and realistic practice of surgical skills. However, the majority of these simulators focus on training low-level technical skills, providing only prototypical surgical cases. For many complex procedures, this approach is deficient in representing anatomical variations that present clinically, failing to challenge users’ higher-level cognitive skills important for navigation and targeting. Surgical simulators offer the means to not only simulate any case conceivable, but to test novel approaches and examine factors that influence performance. Unfortunately, there is a void in the literature surrounding these questions. This …
The Role Of Visualization, Force Feedback, And Augmented Reality In Minimally Invasive Heart Valve Repair, Maria E. Currie
The Role Of Visualization, Force Feedback, And Augmented Reality In Minimally Invasive Heart Valve Repair, Maria E. Currie
Electronic Thesis and Dissertation Repository
New cardiovascular techniques have been developed to address the unique requirements of high risk, elderly, surgical patients with heart valve disease by avoiding both sternotomy and cardiopulmonary bypass. However, these technologies pose new challenges in visualization, force application, and intracardiac navigation. Force feedback and augmented reality (AR) can be applied to minimally invasive mitral valve repair and transcatheter aortic valve implantation (TAVI) techniques to potentially surmount these challenges. Our study demonstrated shorter operative times with three dimensional (3D) visualization compared to two dimensional (2D) visualization; however, both experts and novices applied significantly more force to cardiac tissue during 3D robotics-assisted …

Visual Perception And Cognition In Image-Guided Intervention, Kamyar Abhari
Electronic Thesis and Dissertation Repository
Surgical image visualization and interaction systems can dramatically affect the efficacy and efficiency of surgical training, planning, and interventions. This is even more profound in the case of minimally-invasive surgery where restricted access to the operative field in conjunction with limited field of view necessitate a visualization medium to provide patient-specific information at any given moment. Unfortunately, little research has been devoted to studying human factors associated with medical image displays and the need for a robust, intuitive visualization and interaction interfaces has remained largely unfulfilled to this day. Failure to engineer efficient medical solutions and design intuitive visualization interfaces …
