摘要： The invention relates to an ultrasound images acquisition system. First, a first sequence of ultrasound images (I1) of an organ (LV) is acquired at a first image rate (IR1). Then a second sequence of ultrasound three-dimensional images (I3D—1) of a sub-volume (S_V1) covering a part of interest (RI/VI) in the first sequence (I1) is acquired at a second image rate (IR2) and a third sequence of ultrasound three-dimensional images (I3D—2) of a reference sub-volume (S_V0) is acquired at the second image rate (IR2). Finally the second and third sequences of three-dimensional images sequences (I3D—1, I3D—2) are compared.

摘要： An ultrasonic diagnostic imaging system is described by which a first sequence of ultrasound images of an organ such as the heart is acquired at a first image acquisition rate. The first sequence preferably images a larger volume or area in which a region of interest is located. Then a second sequence of three-dimensional ultrasound images of a sub-volume covering a part of anatomy of interest in the first sequence is acquired at a second image acquisition rate which is greater than the first acquisition rate. A third sequence of three-dimensional ultrasound images of a reference sub-volume is acquired at the second image rate. The second and third sequences of three-dimensional images are compared, enabling a clinician to focus on synchronism defects in the anatomy of interest with more precision and with a faster acquisition time.

摘要： Aspects of the technology described herein relate to configuring an ultrasound device with ultrasound imaging presets. Some embodiments include configuring an ultrasound device with different sets of imaging parameter values without receiving user input regarding configuration of the ultrasound device between configuration of the ultrasound device with one set of imaging parameter values and configuration of the ultrasound device with another set of imaging parameter values. Some embodiments include automatically configuring an ultrasound device with a set of imaging parameter values based on automatically determining an anatomical location being imaged by the ultrasound device. Some embodiments include automatically configuring an ultrasound device with a cardiac preset when a cardiac region is being imaged and automatically configuring the ultrasound device with an abdominal preset when an abdominal region is being imaged during a FAST or eFAST exam.

摘要： Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

摘要： An ultrasonic diagnostic imaging system produces an image with an extended focal range by transmitting a plurality of beams spaced along an array for multiline reception. The receive multilines of a plurality of transmit beams are spatially aligned and are combined with phase adjustment between the respective receive multilines to prevent undesired phase cancellation. The combined multilines produce the effect of an extended transmit focus so that an image produced using the combined multilines exhibits an extended focal range. To prevent motion artifacts the multiline order is adjustable as a function of image motion.

摘要： An ultrasonic diagnostic imaging system scans a plurality of planar slices in a volumetric region which are parallel to each other. Following detection of the image data of the slices the slice data is combined by projecting the data in the elevation dimension to produce a “thick slice” image. Combining may be by means of an averaging or maximum intensity detection or weighting process or by raycasting in the elevation dimension in a volumetric rendering process. Thick slice images are displayed at a high frame rate of display by combining a newly acquired slice with slices previously acquired from different elevational planes which were used in a previous combination. A new thick slice image may be produced each time at least one of the slice images is updated by a newly acquired slice. Frame rate is further improved by multiline acquisition of the slices.

摘要： An improved imaging system includes a memory-storage unit, a multiple-dimensional image processor configured to convert information within a multiple-dimensional data set to a two-dimensional representation in a plane orthogonal to an operator-identified view axis, and an image-rendering device configured to display the two-dimensional representation of a volume-of-interest contained within the three-dimensional data set, wherein the two-dimensional representation is responsive to pixel values associated with a faceplate orthogonal to the view axis. A method for viewing information includes identifying a view axis that intersects a multiple-dimensional data set, modifying the multiple-dimensional data set to align the multiple-dimension data set responsive to the view axis, locating a portion of a structure-of-interest along a vector parallel to view axis, associating a set of pixels with a faceplate, and generating a composite view in accordance with the faceplate.

摘要： A data management framework for a data communications network. The framework includes a dynamically constructed model of elements of the data communications network. The elements are represented as object instances that are self-descriptive. The model provides a uniform application programming interface that allows a client to dynamically access the elements and dynamically add new elements in performing network management functions. The data management framework may be used for policy management.

摘要： An ultrasonic diagnostic imaging system is described which quantifies regurgitant flow through a mitral valve. A flow quantification processor (34) in the ultrasound system produces a mathematical model of a flow velocity field proximal to a regurgitant orifice. The velocity field model produces values of velocity vectors directed toward the regurgitant orifice. These modeled values are modified for the effects of ultrasound physics and ultrasound system operation to produce expected velocity values. The expected velocity values are compared with actual Doppler velocities measured by the ultrasound system, and the differences accumulated to a mean square error which is used to adjust parameters of the model such as the orifice location and flow velocities. When this iterative processing converges with a desired comparison, parameters derived from the finally adjusted model are used to calculate the true orifice location, flow rate, and volume flow.
