Patent number: 7901358Abstract: A system for acquiring an ultrasound signal comprises a signal processing unit adapted for acquiring a received ultrasound signal from an ultrasound transducer having a plurality of elements. The system is adapted to receive ultrasound signals having a frequency of at least 20 megahertz (MHz) with a transducer having a field of view of at least 5.0 millimeters (mm) at a frame rate of at least 20 frames per second (fps). The signal processing can further produce an ultrasound image from the acquired ultrasound signal.

Patent number: 6142946Abstract: An ultrasonic diagnostic imaging system is provided with cordless scanheads which wirelessly transmit ultrasonic image signals to the imaging system. The transmitted image signals are received by a receiver in the mainframe ultrasound system where they undergo further image processing and are displayed. In a preferred embodiment the scanhead image signals are at least partially beamformed in the scanhead before being transmitted to the ultrasound system, thereby reducing the required transmission bandwidth. The cordless scanheads are battery powered, and are recharged by the ultrasound system when the scanheads are not being used for scanning.Type: GrantFiled: November 20, 1998Date of Patent: November 7, 2000Assignee: ATL Ultrasound, Inc.Inventors: Juin-Jet Hwang, Lauren S.
