Abstract: Systems and methods for providing data for visualization and data for quantification are disclosed herein. The data for visualization may be used to generate images to provide to a user on a display. The data for quantification may be used to calculate various physiologically relevant parameters, such as hepato-renal index (HRI) values. In some examples, the quantification data may not be used to generate images. In some examples, a user may select regions of interest (ROIs) in the images generated from the visualization data and the corresponding quantification data for the ROIs may be used to calculate one or more parameters. The visualization data and quantification data may be generated from different imaging modes or same imaging modes with different data processing in some examples.

Abstract: An ultrasonic diagnostic imaging system produces spatially compounded trapezoidal sector images by combining component frames acquired from different look directions. A virtual apex scan format is used such that each scanline of a component frame emanates from a different point on the face of an array transducer and is steered at a different scanning angle. For different component frames the scanlines are steered at respectively different angles. In an illustrated example, the scanlines of each component frame are incremented by five degrees relative to the corresponding scanlines in a reference component frame. When the component frames are combined for spatial compounding, the maximum number of component frames are combined over virtually the entire image field.

Abstract: The present invention relates to ultrasound imaging systems and methods, more particularly, to ultrasound imaging systems and methods for a multi-plane acquisition for single- or bi-plane real-time imaging modes suitable for ultrasound imaging applications, such as quantification of tumor blood flow and tumor fractional blood volume. An ultrasound imaging apparatus can determine a plurality of image planes to scan through a region of interest, acquire echo information corresponding to each of the image planes, generate image information for each of the image planes, store the image information corresponding to each of the image planes; and display an ultrasound image comprising the region of interest, wherein the ultrasound image is rendered from generated image information for a selected image plane of the plurality of image planes or a bi-plane that is at angle to the plurality of image planes.

Abstract: The present invention relates to a method for providing three-dimensional ultrasound images of a volume (50) and an ultrasound imaging system (10). In particular, the current invention applies to live three-dimensional imaging. To maintain a steady frame rate of the displayed images even if a user changes a region of interest and, therewith, the size of the volume (50) to be scanned, it is contemplated to adjust a density of the scanning lines within the volume (50) as a function of a size of the volume while maintaining a total number of scanning lines across the volume (50).

Abstract: An ultrasonic diagnostic imaging system produces an extended field of view (EFOV) image. A 3D imaging probe is moved along the skin of a patient above the anatomy which is to be included in the EFOV image. As the probe is moved, images are acquired from a plurality of differently oriented image planes such as a sagittal plane and a transverse plane. As the probe is moved the image data of successive planes of one of the orientations is compared to estimate the motion of the probe. These motion estimates are used to position a succession of images acquired in one of the orientations accurately with respect to each other in an EFOV display format. The motion estimates are also used to display a graphic on the display screen which indicates the progress of the scan to the user as the probe is being moved. The progress may be indicated in terms of probe velocity, distance traveled, or the path traversed by the moving probe.
