A method and system for displaying an image associated with an extended field of view is provided. One image comprises a compounded sub-set of the extended field of view. Other images may include an extended field of view image or an image absent compounding from the extended field of view image. The compounded sub-set image is associated with reduced noise as compared to the image absent compounding and more closely resembles an area of the extended field of view image. Where plurality of images are associated with a rotated transducer or scan planes or where a sector or Vector&#xae; scan pattern is used, the compounded sub-set provides spatial compounding associated with different angles of incidence to the region of interest, increasing speckle reduction.

Compound image display system and method

An ultrasound imaging system produces three-dimensional tissue/flow images by first computing a plurality of separate two-dimensional tissue images and two-dimensional flow images. Separate tissue and flow volumes are created by applying the tissue and flow images to a three-dimensional construction algorithm. Each of the separate tissue and flow volumes is analyzed using a three-dimensional rendering algorithm to produce a rendered tissue and flow image. The separately rendered tissue and flow images are combined to produce the combined tissue/flow image. In addition, the present invention provides visual cues that allow a user to create more even scans. The invention also includes a method for correcting for probe movement. The invention also produces an image that is calculated from the partial volume data as it is being created to give a user feedback on the quality of the image they are producing. Finally, the invention compensates for variations in the cardiac cycle when selecting data to be used in creating a flow volume.

Three-dimensional tissue/flow ultrasound imaging system

An ultrasonic imaging system and method is described in which the actual dimensions of images of tissue acquired with a moving transducer (22) are displayed. Since an image is distorted based upon the direction a transducer probe moves relative to the acoustic scanning direction of the transducer (22), the probe motion direction and the acoustic scanning direction are initially determined. If the probe is moving in the same direction as the scanning direction, the acoustic beam scanning speed of the moving probe relative to the tissue is determined by summing the acoustic beam scanning speed without probe motion with the probe speed. If the probe is moving in the opposite direction as the scanning direction, the acoustic beam scanning speed of the moving probe relative to the tissue is determined by taking the difference between the acoustic beam scanning speed without probe motion and the probe speed. The actual width of the image as represented in each pixel of a frame (32) acquired while the probe is moving is derived based upon a ratio of the acoustic beam scanning speed of the moving probe relative to the tissue to the acoustic beam scanning speed without probe motion. Finally, the actual dimensions of the image are displayed based upon the derived width of the image as represented in each pixel of the frame (32).
