Abstract: An ultrasound probe and an ultrasound imaging system include a 2D transducer array including a plurality of transducer elements organized to form a transmit aperture and a receive aperture, where the transmit aperture and the receive aperture do not overlap with each other. The probe and system include a plurality of distribution nodes and a plurality of sets of transmit switches. Each set of transmit switches includes a plurality of transmit switches and each set of transmit switches is associated with a different one of the plurality of transducer elements in the transmit aperture. Each set of transmit switches is configured to selectively connect the associated transducer element to any one of the plurality of distribution nodes when in a continuous-wave Doppler mode.

Abstract: Methods and systems for monitoring a transducer array in an ultrasound probe are provided. One method includes acquiring ultrasound data using an ultrasound probe during an imaging mode of operation, wherein the ultrasound data includes echo information. The method further includes comparing the echo information from a plurality of transducer elements of a transducer array of the ultrasound probe during the imaging mode of operation, wherein the echo information is non-beamformed signal data. The method also includes determining non-uniformity information for the transducer array using the compared echo information during the imaging mode of operation.

Abstract: A system for presenting multiple parallel slices comprises a display for displaying ultrasound data comprising 3D Doppler data over time. A user interface defines a proximal plane and a distal plane within the ultrasound data that are parallel to one another. The proximal and distal planes define a region of interest (ROI). A signal processor automatically extracts at least two slices based on the ultrasound data within the ROI. The at least two slices are parallel with respect to each other and are displayed on the display.

Abstract: Systems and methods for automatically adjusting an analog time gain compensation utilized in ultrasound imaging systems are provided. In one embodiment, a method for ultrasound imaging comprises applying an analog gain to a first echo signal based on a depth and a direction of the first echo signal, wherein the analog gain is automatically adjusted based on a peak amplitude of a second echo signal in a preceding ultrasound image. In this way, a signal-to-noise ratio of echo signals may be optimized, thereby improving the quality of ultrasound images generated from the echo signals.
