  • 3-D ultrasound recording device
    Patent number: 6605041
    Abstract: The present invention is related to a device for recording three-dimensional ultrasound images. The device includes an ultrasound head which can be freely moved by hand, an ultrasound recording apparatus, an image processing system, and a position detection system. The position detection system has an analyzing unit and at least two sensors for detecting electromagnetic waves so that the position and orientation of the ultrasound head and, thus, the position and orientation of the ultrasound section images in space can be determined.
    Type: Grant
