Remarkable new imaging technology developed by researchers at the University of Wisconsin can not only capture the heart in 3D showing blood flow, direction, and velocity, but can also show them relating to a fourth dimension - time. The procedure is fast, and requires no invasive procedures, no contrast agent or general anesthesia and could have significant consequences for patients at risk of cardiac problems. Read More

The system will be able to see real-time black and white or color inner body images on the screen of the Vscan and data can be also be saved and reviewed at a later date. Read More
