    Abstract: An ultrasonic apparatus for scanning an image field of a subject extending in substantially opposite directions from the middle of said field to lateral extremes of said field with beams of ultrasound which are transmitted and received in a pattern in which the beams are spatially adjacent to each other over said image field. This apparatus has means for minimizing multipath artifacts, comprising means for sequentially transmitting and receiving ultrasonic beams in successive beam directions along which the consecutively transmitted and receive beams are substantially spatially separated, and in an alternate manner. This means may include means for sequentially transmitting and receiving beams in successive beam directions that are divergent from a first beam direction located at a first location in said image field alternately each side of the first beam direction; and/or means for sequentially transmitting and receiving beams in successive beam directions that are convergent from two opposite beam directions alternately towards the center of said image field.

    Abstract: An ultrasonic diagnostic imaging system is provided which scans an image region to receive a plurality of spatially arranged lines of ultrasonic image information signals. These ultrasonic line information signals are used in an interpolater to interpolate one or more lines which are spatially interlineated between each pair of spatially adjoining received lines. These interpolated lines are produced using either the received RF or demodulated IF ultrasonic image information signals. The interpolated lines are produced prior to scan conversion, and preferably prior to nonlinear processing such as detection or log compression to reduce spatial aliasing artifacts. In one preferred embodiment the interpolater comprises a transversal filter of four taps which is responsive to received line information signals from a common range or depth. In a second embodiment the interpolater is adaptively responsive to motion to select samples for interpolation which would be spatially at the same range in the absence of motional effects.

    Abstract: A technique for scanning an image field with adjacent beams of ultrasonic energy is provided in which initially transmitted beams are transmitted along beam directions down the center of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at increasing lateral locations in said field with respect to the locations of the initially transmitted beams until the full image field has been scanned. In one alternative embodiment initially transmitted beams are transmitted along beam directions at the lateral sides of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at lateral locations which converge toward the center of the image field until the full image field has been scanned. In another alternative embodiment initially transmitted beams are transmitted on one side of the center of the image field, subsequent beams diverge from the locations of the initially transmitted beams, and concluding beams laterally converge at a location on the other side of the center of the image field.
