    Abstract: A 3-D endocavity ultrasound probe includes an instrument holder having a channel configured to guide an instrument. The 3-D endocavity ultrasound probe further includes an elongate shaft with a center line, a first side, a second opposing side with a recess configured to receive the instrument holder over the center line, and a drive system disposed in the first side and not over the center line. The 3-D endocavity ultrasound probe further includes a probe head disposed at an end of the shaft. The probe head includes a rotatable support and a transducer array coupled to the rotatable support. The drive system is configured to rotate the rotatable transducer array support thereby rotating the transducer array. The channel extends along the center line thereby providing an instrument path in-plane with a sagittal plane of the elongate shaft.

    Abstract: An ultrasound imaging system (100) includes a transducer array (102). The transducer array includes a first set of transducer elements (206 or 208, 302 or 304) and a second set of transducer elements (208 or 206, 304 or 302). The first and second sets of transducer elements includes long axes and are angularly offset from each other by a non-zero angle with respect to the long axes. The ultrasound imaging system further includes a velocity processor (120) that processes echoes received by the first and second sets of transducer elements and determines an axial and two transverse flow velocity components based on the received echoes.

    Abstract: An apparatus includes a transducer array with a plurality of CMUT elements. Each of the plurality of CMUT elements includes a first end and a second end. The transducer array further includes a bias network that is electrically connected with the first and second ends of the plurality of CMUT elements. The bias network applies a first bias voltage to the first end of the plurality of CMUT elements and a second bias voltage to the second end of the plurality of CMUT elements. The first and second bias voltages bias the plurality of CMUT elements. A method includes biasing, with bias network, a CMUT element of an transducer array using a bipolar signal that includes a first bias voltage and a second bias voltage, transmitting, by a transmit circuit, a transmit signal to the CMUT element, receiving, by a receive circuit, a receive signal from the CMUT element.

    Abstract: An ultrasound imaging includes a beamformer configured to process ultrasound echo signals generated by the plurality of elements of a transducer array. The beamformer includes a delay processor configured to generate a delay for each of the signals and apply the delays to corresponding signals and a summer configured to sum the delayed signals to produce an image. The delay processor includes a spatio-temporal processor configured to computed delays based on time-of-flight calculations from a center of the elements to one of a transmit focal point, a virtual source or a plane, a spatial correction processor configured to compute delay corrections for the computed delays, an adder configured to add the delay corrections to the computed delays to produce corrected delays, and a delay component configured to delay each of the signals with a corresponding corrected delay.

    Abstract: An ultrasound imaging system include a console with transmit circuitry configured to generate an excitation electrical pulse that excites transducer elements of a probe to produce an ultrasound pressure field and configured to receive an echo signal generated in response to the ultrasound pressure field interacting with tissue. The console further includes receive circuitry configured to convert the echo signal into an electrical signal, and an echo processor configured to generate a live ultrasound image based on the electrical signal into. The console further includes a tracking processor configured to extract, in real-time, a feature common to both the live ultrasound image and previously generated volumetric image data from at least the live ultrasound image, and register, in real-time, the live ultrasound image with previously generated volumetric image data based on the common feature extracted in real-time to create the fused image. A display displays the fused image.

    Abstract: An ultrasound imaging method includes identifying a two-level pulse coding scheme (519), which includes a positive voltage value and a negative voltage value, for harmonic imaging. The method further includes driving a pulse generator (510) with the two-level pulse coding scheme. The method further includes producing, with the pulse generator, an excitation pulse. The method further includes routing the excitation pulse through a switch (518) to an ultrasonic transducer array (504), which transmits a first ultrasound signal in response thereto. The method further includes receiving first echoes generated in response to the excitation pulse. The method further includes processing the first echoes to extract a harmonic signal. The method further includes beamforming the harmonic signal to produce an image.
