摘要： A set of N×M signals are acquired from an object, where N is the number of array elements and M corresponds to variations in data acquisition and/or processing parameters. The parameters include transmit aperture functions, transmit waveforms, receive aperture functions, and receive filtering functions in space and/or time. A coherence factor is computed as a ratio of the energy of the coherent sum to the energy of the at-least-partially incoherent sum of channel or image signals acquired with at least one different parameter. Partial beamformed data may be used for channel coherence calculation. For image domain coherence, a component image is formed for each different transmit beam or receive aperture function, and a coherence factor image is computed using the set of component images. The coherence factor image is displayed or used to modify or blend other images formed of the same region.

摘要： Aberration estimation uses cross correlation of receive-focused transmit element data. A set of sequentially fired broad transmit beams insonify an object from different steering angles. Each transmit beam emanates from an actual or a virtual transmit element. For every firing, a receive beamformer forms a transmit element image of the insonified region by focusing the received signals. An estimator estimates aberration by cross correlating or comparing the transmit element images. Where a virtual transmit element is used, the virtual transmit element images are back propagated to an actual transmit element position before aberration estimation. The estimations are used to form corrected transmit element images which are then summed pre-detection to form a high-resolution synthetic transmit aperture. Alternatively, the estimations are used to improve conventional focused-transmit imaging.
摘要翻译：畸变估计使用接收发射单元数据的互相关。一组顺序发射的宽发射光束使不同转向角的物体失真。每个发射波束从实际或虚拟发射元件发出。对于每次触发，接收波束形成器通过聚焦接收到的信号来形成声音区域的发射元件图像。估计器通过交叉相关或比较发射元件图像来估计像差。在使用虚拟发射元件的情况下，虚拟发射元件图像在像差估计之前被反向传播到实际发射元件位置。这些估计用于形成经校正的发射元素图像，然后将它们相加预检测以形成高分辨率合成发射孔径。或者，估计用于改进传统的聚焦传输成像。

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： Ultrasound imaging adapts as a function of a coherence factor. Various beamforming, image forming or image processing parameters are varied as a function of a coherence factor to improve detail resolution, contrast resolution, dynamic range or SNR. For example, a beamforming parameter such as the transmit or receive aperture size, apodization type or delay is selected to provide maximum coherence. Alternatively or additionally, an image forming parameter, such as the number of beams for coherent synthesis or incoherent compounding, is set as a function of the coherence factor. Alternatively or additionally an image processing parameter such as the dynamic range, linear or nonlinear video filter and/or linear or nonlinear map may also adapt as a function of the coherence factor.

摘要： The depth buffer of a GPU is used to derive a surface normal or other surface parameter, avoiding or limiting computation of spatial gradients in 3D data sets and extra loading of data into the GPU. The surface parameter is used: to add shading with lighting to volume renderings of ultrasound data in real time, to angle correct velocity estimates, to adapt filtering or to correct for insonifying-angle dependent gain and compression. For border detection and segmentation, intersections with a volume oriented as a function of target structure, such as cylinders oriented relative to a vessel, are used for rendering. The intersections identify data for loading into the frame buffer for rendering.

摘要： To improve real time 3D imaging performance, acquisition, beamforming, coherent image forming and/or image processing parameters are varied as a function of the viewing direction selected by the user. For example, the scan planes are oriented relative to the viewing direction. As a result rapid 3D rendering is provided without complex additional data interpolation or other 3D rendering processes. In another example, data along the lateral axis that is perpendicular to the viewing direction (i.e., display lateral axis) is acquired with parameters adapted to maximize field of view, detail and contrast resolution, while data along the lateral axis that is parallel to the viewing direction is acquired with compromised field of view, detail or contrast resolution. As a result, a high volume rate 3D imaging is achieved with 2D-equivalent detail resolution, contrast resolution and field of view along the display lateral axis.

摘要： A medical ultrasound diagnostic imaging system includes a delay system that applies a composite delay profile to signals to or from respective transducer elements. One composite delay profile includes a first, substantially point-focus delay profile for a first set of the transducer elements and a second, substantially point-focus delay profile for a second set of the transducer elements. The first and second delay profiles cause ultrasonic energy from the respective first and second sets of the transducer elements to constructively add at first and second respective spaced focal zones in either transmit or receive. Another composite delay profile includes first and second portions that substantially correspond to respective parts of a point-focus delay profile, and third and fourth portions that are intermediate the point-focus delay profile and respective tangents.

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.
