    Abstract: A steerable medical catheter includes a tubular body having a longitudinal axis and a distal portion for insertion into a subject, a first pull wire, a second pull wire, and a piezoelectric transducer. The piezoelectric transducer includes a first electrode and a second electrode. At the distal portion of the catheter the first pull wire and the second pull wire are each mechanically coupled to the tubular body at respective first and second offset positions with respect to the longitudinal axis for imparting a curvature on the distal portion of the catheter. At the distal portion of the catheter the first pull wire is electrically connected to the first electrode of the piezoelectric transducer and the second pull wire is electrically connected to the second electrode of the piezoelectric transducer.

    Abstract: A medical ultrasound acquisition-data analysis device acquires channel data (144) via ultrasound received on the channels, uses the acquired channel data to estimate data coherence and derive dominance of an eigen-value of a channel covariance matrix and, based on the estimate and dominance, distinguishes microcalcifications (142) from background. Microcalcifications may then be made distinguishable visually on screen via highlighting, coloring, annotation, etc. The channel data operable upon by the estimating may have been subject to beamforming delays and may be summed in a beamforming procedure executed in the estimating. In the estimating and deriving, both field point-by-field point, multiple serial transmits (116, 118) may be used for each field point. In one embodiment results of the estimating and deriving are multiplied point-by-point and submitted to thresholding.

    Abstract: A processor (28) in communication with ultrasound probe (10) is configured to: generate an initial ultrasound image including an anatomical feature of a patient, an image artifact, and a region of interest obscured by the image artifact; and determine depths of the anatomical feature and region of interest. The processor generates a first ultrasound image with focal depth of the transmit and receive beams set to the depth of the anatomical feature, so the anatomical feature and the image artifact are enhanced and the appearance of the region of interest is decreased. The processor generates a second ultrasound image with the focal depth of the transmit and receive beams set to the depth of the region of interest, so that the appearance of the anatomical feature and the image artifact is decreased, and the region of interest is enhanced, and generates an output based on the first and second images.
