Presence is often used as a quality measure for virtual reality experiences. It refers to the sensation of “being there” that users feel while wearing a head-mounted display. In contrast, simulator sickness refers to the feeling of unease of some users while experiencing virtual motion. Nowadays, many virtual reality games do not allow the player to walk, trying to minimize the generation of un...

Realistic generation of variable anatomical organ models and pathologies are crucial for a sophisticated surgical training simulator. A training scene needs to be different in every session in order to exhaust the full potential of virtual reality based training. We previously reported on a cellular automaton able to generate leiomyomas found in the uterine cavity. This paper presents an altern...

Virtual reality has been introduced to the medical field and it is now used in medical education as an alternative high fidelity simulator. The major components to successful learning that has contributed to the efficacy of the virtual reality system are the ability to provide repetitive practice under controlled environment, self-directed learning and proved construct validity. This review eva...

Purpose: Identify and prospectively investigate simulated ultrasound-guided targeted Liver Biopsy performance metrics as differentiators between levels of expertise in Interventional Radiology. Materials and Methods: Task analysis produced detailed procedural step documentation allowing identification of critical procedure steps and performance metrics for use in a virtual reality ultrasound-gu...

Computer systems are taking an important role in the field of medicine with the introduction of electronic biomedical devices in diagnosis and treatment, where medical records obtained from the devices are documented and processed as reference to medical panels. The capability of latest computed tomography technology in generating three-dimensional patient model for graphical representation is ...
