Butterfly TeleGuidance for Remote Ultrasound Exams During COVID Pandemic
Telemedicine has been around for over a decade in various forms, but the COVID-19 epidemic has turned a convenience into a necessity. Clinical practices that never seriously considered using telemedicine are now performing virtual house calls with their patients. However, although it’s possible to do a lot through a video call, many procedure (Read more...)
Personalized Blood Flow Modeling Benefits from Virtual Reality Interface
Researchers at Duke University have developed a fluid dynamics simulator that can model blood flow within the body, including the motion of individual blood cells. The researchers hope that the system could eventually be used by clinicians to model blood flow for individual patients and help with treatment decisions, such as stent placement. By tes (Read more...)
