    Abstract: The invention provides a portable ultrasonic imaging probe directly connectable to an off-the-shelf laptop computer. The probe produces raw digitized data comprising envelope detected ultrasound echo data from an array of ultrasound transducers, and transmits the data to the host computer thereby enabling the host computer to form real-time ultrasonic images of human tissue without the need for any additional electronics. In particular embodiments, the probe includes a plurality of transmit switches configured to connect a transmitting group of the ultrasound transducers to a pulser; a plurality of receive switches configured to connect a receiving group of the ultrasound transducers to analog summing, amplification and signal processing circuitry; and a transmit/receive controller which selects which of said ultrasound transducers are in the transmitting group and which of said ultrasound transducers are in the receiving group. The ultrasound transducers may be conventional or micromachined ultrasound transducers.

    Abstract: An ultrasound probe includes a piezoelectric material, a signal electrode provided on the piezoelectric material, and a ground electrode provided on the piezoelectric material. Ultrasound waves are emitted from the piezoelectric material by applying a voltage between the signal electrode and the ground electrode. A switching element switches a connection between the signal electrode and the ground electrode from a closed state to an open state, and vice versa, in accordance with a control signal for controlling whether or not to emit the ultrasound waves. The switching element changes from the closed state to the open state in accordance with the control signal for emitting the ultrasound waves, and changes from the open state to the closed state in accordance with the control signal for suspending emission of the ultrasound waves. The ultrasound probe can maintain the reliability of the piezoelectric material when the temperature is high or changes suddenly.
