Embodiment Construction
[0023] FIG. 1 is a block diagram of an ultrasound probe 100 including a transducer 110 . Transmit circuitry 120 is disposed within probe 100 to generate electrical pulses that are applied to transducer 110 to generate a transmit beam within the subject. Transmit circuitry 120 generates the electrical pulses in response to signals received from beamformer circuitry 130, which applies a time delay for focusing the transmit pulses as desired. Beamformer circuitry 130 is arranged to receive reflected pulses from transducer 110 . The beamformer circuit 130 may also apply a time delay and / or gain control to set the power level of the reflected beam. A transmit / receive (T / R) switch 120 is connected to transducer 110, transmit circuitry 120, and beamformer circuitry 130 for isolating transmitted pulses from reflected pulses. In a preferred embodiment, the ultrasound probe 100 is a microbeamformer ultrasound probe with thousands of transducers to enable three-dimensional imaging. Al...
