An ultrasound imaging system and method includes acquiring first 4D ultrasound data of a first partial volume for a first period of time that is longer than an estimated cardiac period and acquiring second 4D ultrasound data of a second partial volume for a second period of time that is longer than the estimated cardiac period. The system and method includes combining the first 4D ultrasound data with the second 4D ultrasound data to generate 4D ultrasound data of a region-of-interest. The system and method also includes generating and displaying an image based on the 4D ultrasound data.

Ultrasound imaging system and method

An method and system for ultrasound imaging includes accessing a first cross-plane image of a first plane. The method and system includes identifying a first region including a structure in the first cross-plane image. The method and system includes accessing a second cross-plane image of a second plane, where the second plane intersects the first plane. The method and system includes identifying a second region including the structure in the second cross-plane image. The method and system includes automatically configuring acquisition parameters based on at least one of the first region and the second region. The method and system includes implementing the acquisition parameters to acquire data of the structure. The method and system includes generating an image from the data and displaying the image.

Method and system for ultrasound imaging with cross-plane images

A method for assessing mechanical properties of an elastic material includes obtaining volumetric ultrasound data sets of the elastic material in two different states of compression. First ultrasound image data of a first hypersurface region of interest (ROI) is selected from a first of the data sets, and second ultrasound image data of a second hypersurface ROI is selected from a second of the data sets. The first ultrasound image data and the second ultrasound image data are compared to determine motion within the elastic material. If out of ROI motion of the elastic material is not less than a specified or predetermined amount and if an allowed number of iterations has not been met, the orientation of at least one ROI is changed and a portion of the process is iterated. Otherwise, an indication of motion resulting from the applied compression within the elastic material is displayed.

A transducer assembly is provided including a transducer array comprising a plurality 'M' of transducer elements and a sub-aperture processor comprising a plurality 'P' of input channels and an output channel. The plurality &#x2018;P&#x2019; of input channels is coupled to the &#x2018;M&#x2019; transducer elements and a plurality &#x2018;R&#x2019; of switching elements in operative association with the output channel of the sub-aperture processor to switchably couple the output channel to at least one of a plurality of &#x2018;N&#x2019; system channels.

Certain embodiments of the present invention provide a system, method and computer instructions for compression of four dimensional data. In an embodiment, a system for compression of four dimensional data includes: a compression module configured to compress four dimensional data, wherein the data includes a first three dimensional volume and a second three dimensional volume, and wherein the compression module compresses the data by compressing the first volume and compressing a difference between the first volume and the second volume. In an embodiment, the data may further include a third three dimensional volume and the compression module may further compress the data by compressing a difference between the second volume and the third volume, for example. The system for compression of four dimensional data may also include, an input module(s), a decompression module and an output module(s), for example.

A method for correcting motion artifacts within a volumetric data set is provided. The method includes obtaining a volumetric data set containing spatial and temporal information regarding an object. The volumetric data set is organized into data slices such that at least two adjacent data slices are representative of a common physical slice within the object at different points in time. The relative motion between adjacent data slices in determined for the slices of the volumetric data set and used to correct for the relative motion between said adjacent slices.

A method for three dimensional (3D) segmentation of an object is provided. The method obtains a volumetric data set containing object data and non-object data in proximity to the object data, the object data having a reference axis extending through the object data. The method defines at least one reference slice and multiple object slices within the volumetric data set, the reference slice and the object slices intersecting one another along the reference axis and containing the reference axis. Reference points are determined within the reference slice at edges of the object data. With reference points determined, the method generates an estimated contour extended through the reference and object slices based on the reference points, the estimated contour intersecting the object slices to define estimated contour points. The method then adjusts the estimated contour points until corresponding substantially to actual contour points of the object data.

Method and apparatus for detecting a contour of an object within an image is provided. A user interface is used to select first and second points within the object. A processor detects first and second subcontours based on the first and second points, respectively; and the first and second subcontours are based on detected edges. The detected edges are representative of non-uniformities within the image. The processor defines subcontours around each of the points, and the subcontours are combined into a contour.

Method and apparatus for acquiring and processing a volumetric scan of a periodically moving object having uneven periods of time are included. A volumetric scan is performed of a periodically moving object. A time interval of a periodic movement of the periodically moving object is identified within the volumetric scan. The volumetric scan is divided into volume subsets based on the time interval. The periodic movement is analyzed to determine a correction between adjacent volume subsets, and the time interval is adjusted based on the correction.

Method and apparatus for acquiring and processing a volumetric scan of a periodically moving object. A volumetric scan is performed of the periodically moving object which repeats a cycle of movement over time. A time interval of the periodic movement of the object is identified within the volumetric scan, and the volumetric scan is rearranged based on the time interval.
