Virtual Reality Improves Complex SurgeriesVirtual reality and 3-D modeling are now making complex surgeries easier not only for patients, but also for medical students, doctors, radiologists, and surgeons. See how they are being used to educate everyone involved.
Medical imaging : X-Rays, CT, MRI, ultrasound, and virtual realityThis comprehensive overview assesses a number of noninvasive ways to look inside the human body. Segment one addresses the limitations of X-ray and fluoroscopic technologies and introduces computed tomography, magnetic resonance imaging, and ultrasound. Segment two describes how images are digitized and discusses the practical difficulties in achieving a clear image. Segment three demonstrates how computers can be used to enhance image definition. And segment four features two virtual reality programs that allow medical students to practice performing a craniotomy to remove a tumor and percutaneous rhizotomy to treat trigeminal neuralgia.
