  • Portable ultrasound diagnostic system with handsfree display
    Patent number: 6126608
    Abstract: An ultrasound diagnostic system with a display wearable by a user such that the display does not fully occupy a user's hand during system operation. In one embodiment, the display is provided in a main unit that is shaped to fit on top of the forearm of the system user. An attachment mechanism of the main unit encircles the forearm. The main unit mounted on the arm receives data from a handheld scanhead used to obtain the ultrasonic images. In an alternate embodiment, the main unit may be operatively connected to a strap that loops around the neck of a user to allow the display to be suspended in front of the system user. Peripherals, such as a keyboard and a printer, may be operatively connected to the main unit by way of a wireless interface, such as an infrared connection.
