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...

Abstract

A hybrid integrated circuit package for a microbeamformer in an ultrasound probe includes a substrate, a driver circuit for generating transmit pulses to be transmitted to the transducer elements of the probe for producing a transmit beam, and a beamformer circuit including time delay circuits and a summation circuit, the time delay circuits being operatively arranged for receiving a plurality of reflected pulses from the transducer elements and delaying the reflected pulses and the summation circuit operatively arranged summing groups of the delayed reflected pulses for producing beamformed signals. The driver circuit is part of a high voltage integrated circuit device including said driver circuit. At least a portion of the beamformer circuit is part of a low voltage integrated circuit device, wherein the high voltage integrated circuit and the low voltage integrated circuit are mounted on the substrate.

Description

technical field [0001] The present invention relates to a hybrid integrated circuit (IC) for an ultrasound beamformer probe that simultaneously provides the high voltage requirements of the transducer element interface and the high density functional requirements of the control and beamforming functions. Background technique [0002] Medical ultrasound imaging systems are used for non-invasive real-time viewing of the internal structures of the human body. An ultrasound imaging system includes a transducer array for transmitting and receiving ultrasound pulses. Each transducer is a piezoelectric element. The transmit beamformer circuit applies electrical pulses to individual transducers within the transducer array in a specific timing sequence to generate a transmit beam. The transmitted beam is reflected by tissue structures with completely different acoustic properties. The reflected beam is converted by the receiving transducer into electrical pulses, which are convert...
