Abstract: Two-dimensional transducers arrays for ultrasound imaging is disclosed. The two-dimensional arrays are suitable for formation of two-dimensional (2D) and/or three-dimensional (3D) ultrasound images. The two-dimensional arrays are suitable for real-time 2D and/or 3D ultrasound imaging. The bowtie transducer arrays and the rectangular transducer arrays are suitable for real-time 2D and/or 3D ultrasound imaging.

Abstract: An ultrasound system is disclosed that utilizes an arbitrary waveform generator, memory, and an ultrasound transducer. A plurality of excitation waveforms are stored in the memory and may be output from the arbitrary waveform generator to an ultrasound transducer. At least one first excitation waveform is stored in the memory and includes an excitation portion with no damping portion (e.g., for one ultrasound procedure; such that an output from the ultrasound transducer is of a first bandwidth). At least one second excitation waveform is stored in the memory and includes an excitation portion and a damping portion (e.g., for another ultrasound procedure; such that an output from the ultrasound transducer is of a second bandwidth that is larger than the first bandwidth).

Abstract: Improved ultrasound imaging using coherence estimation of a beamformed signal. Ultrasound imaging using coherence estimation of a beamformed signal as described herein may be performed by applying a plurality of filters to the beamformed signal to generate a plurality of filtered beamformed signals. Normalized cross-correlation may be performed on a plurality of pairs of filtered beamformed signals to determine a coherence coefficient corresponding to each pixel of an ultrasound image, which may be used to construct a coherence estimation ultrasound image.
