Ultrasound Trainer Simulation

UST Simulation

This robust, turnkey mixed reality simulator is designed to help novices understand and acquire fundamental cross-sectional literacy and ultrasonography (US) skills. Based on the premise that it is a cognitive overload for novices to learn both US skills and unfamiliar anatomy, the trainer gets rid of anatomy as a “distraction” so that learners can focus on hands-on US skills acquisition. Anatomy is instead replaced by virtual regular and familiar 3D objects like cylinders, cubes and pyramids. Designed for austere environments, this procedure-agnostic simulator does not require wireless or internet access or wet fluids; accepts 110/220V, 50/60Hz. It can be unpacked/set up/be operational by an unfamiliar person in 5-7 minutes. The portable simulator fits inside a military-spec padded case with inbuilt wheels and telescoping pull-handle that meets airline checked luggage size limits (L+W+H=60”), weight < 70lbs.
