Abstract
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.
