Design And Evaluation Of Neurosurgical Training Simulator, Trinette L. Wright
Design And Evaluation Of Neurosurgical Training Simulator, Trinette L. Wright
Electronic Thesis and Dissertation Repository
Surgical simulators are becoming more important in surgical training. Consumer smartphone technology has improved to allow deployment of VR applications and are now being targeted for medical training simulators. A surgical simulator has been designed using a smartphone, Google cardboard 3D glasses, and the Leap Motion (LM) hand controller. Two expert and 16 novice users were tasked with completing the same pointing tasks using both the LM and the medical simulator NeuroTouch. The novice users had an accuracy of 0.2717 bits (SD 0.3899) and the experts had an accuracy of 0.0925 bits (SD 0.1210) while using the NeuroTouch. Novices and …
Exploiting Temporal Image Information In Minimally Invasive Surgery, Jonathan Mcleod
Exploiting Temporal Image Information In Minimally Invasive Surgery, Jonathan Mcleod
Electronic Thesis and Dissertation Repository
Minimally invasive procedures rely on medical imaging instead of the surgeons direct vision. While preoperative images can be used for surgical planning and navigation, once the surgeon arrives at the target site real-time intraoperative imaging is needed. However, acquiring and interpreting these images can be challenging and much of the rich temporal information present in these images is not visible. The goal of this thesis is to improve image guidance for minimally invasive surgery in two main areas. First, by showing how high-quality ultrasound video can be obtained by integrating an ultrasound transducer directly into delivery devices for beating heart …
