摘要： Adaptive line synthesis is provided. Line synthesis of collinear receive beams responsive to spatially distinct transmit beams is a function of many parameters, such as spatial or temporal frequency response of one or more of the receive beams, synthesis function, number of receive beams synthesized, or acquisition sequence. One or more of these parameters is set or adapts as a function of processor estimated or user provided information. By adapting the line synthesis, the performance and image quality is optimized as appropriate for the received data or desired imaging, such as detail resolution, contrast resolution, temporal resolution, shift-invariance and penetration.

摘要： Transmit multibeams insonify an object with multiple noncollinear transmit beams fired substantially simultaneously. The noncollinear beams are along different scan lines of same scan geometry, or they belong to scan lines of different scan geometries. One or more receive beams are formed in parallel in response to each of the noncollinear beams. The scan geometry and/or center frequency is varied between the noncollinear transmit beams of a transmit event. By scanning the transmit multibeam, and varying the scan geometry and/or frequency between the noncollinear transmit beams of a transmit event, multiple component images are generated for compounding. The component images are scan-converted (if scan geometries are different), weighted and combined after envelope detection.

摘要： Multiple apexes or intersections of scan lines are used to control the desired scan region for three dimensional scanning. Where a two dimensional transducer array is not square or circular or if the element spacing in azimuth and elevation is unequal, multiple apexes allow for optimization of the scanned volume to the transducer characteristics. The different apexes may be spaced from each other and relative to the transducer at various locations. Distributed patterns of apexes may be provided, such as spacing a plurality of apexes along a line in elevation and another set of apexes along a line in azimuth.

摘要： Contrast agent destruction transmissions have reduced biological effect in medical diagnostic ultrasound. Ramping-up amplitude and/or ramping-down frequency reduce biological effect. The amplitude ramps up linearly or non-linearly. The change in amplitude or frequency occurs over a single waveform or over a sequence of separate transmissions. An envelope of the single waveform or the sequence of separate transmissions has a non-uniform, asymmetrical, symmetrical, rectangular or other shape. For example, the frequency ramp-down is provided with a non-Gaussian envelope. The amplitude ramp-up or frequency ramp-down is a progressively increasing destructive characteristic or ability, destroying contrast agent at different regions relative to focal regions with a minimum of acoustic energy.

摘要： Standardized or preset views for a given application are used to assist in volumetric scanning and diagnosis. By displaying one or more images of a standard view during acquisition, the scan is guided to assure proper positioning of the volumetric scan. The location of a user identified view within the volume is used to determine the location of an additional view. The spatial interrelationship of the views within the standard or preset set of views allows generation of images for each of the views after the user identification of one of the views within the volume. Identification of landmarks associated with a view may be used for more efficient or accurate feature recognition, more likely providing images for the standard views.

摘要： Multiple receive beams are formed for each transmission for rapid acquisition. The receive aperture is shifted as a function of the position of each receive beam. Multiple receive beams with differently positioned apertures are formed in response to a single transmit beam. Alternatively or additionally, the apodization varies as a function of the position of the receive beam relative to the transmit beam. Multiple receive beams with different apodization profiles are formed in response to a single transmission. The apodization and/or aperture variations in different receive beams may reduce geometric distortion and/or clutter levels for receiving multiple beams in response to a single transmission.

摘要： Methods and systems for varying a pattern as a function of steering angle for medical imaging with a multidimensional array are provided. Transmit waveform, delay, phase or apodization patterns in addition to delays, phases or apodization for focusing are used with a multidimensional array. By applying a periodic variation perpendicular to the steering direction, the effects of grating lobes due to the variation may be reduced. Along the steering direction, additional offsets are not provided, but may be provided. This different or non-existent offsets provide less grating lobe clutter. The transmit aperture is adjusted to be parallel to a direction of steering of non-normal transmit scan line or scan lines. The variation pattern is selected to result in enhancement or isolation of one or more frequency bands from one or more other frequency bands, such as isolation of second harmonic information from fundamental transmit frequency information.
