摘要： Aspects of the technology described herein relate to configuring an ultrasound system with imaging parameter values. In particular, certain aspects relate to configuring an ultrasound system to produce a plurality of sets of ultrasound images, each respective set of the plurality of sets of ultrasound images being produced with a different respective set of a plurality of sets of imaging parameter values; obtaining, from the ultrasound system, the plurality of sets of ultrasound images; determining a set of ultrasound images from among the plurality of sets of ultrasound images that has a highest quality; and based on determining the set of ultrasound images from among the plurality of sets of ultrasound images that has the highest quality, automatically configuring the ultrasound system to produce ultrasound images using a set of imaging parameter values with which the set of ultrasound images that has the highest quality was produced.

摘要： An ultrasonic diagnostic imaging system is described which quantifies regurgitant flow through a mitral valve. Echo signals received by an ultrasound probe (10) are used to produce an image of a regurgitant flow region, and are processed by a wall filter having a response characteristic which peaks at an intermediate sampling rate between zero and the Nyquist limits. This response characteristic is thus highly sensitive to lower flow rates which may be anticipated in a flow velocity field proximal a regurgitant orifice. Echo signals passed by the wall filter are Doppler processed and used to quantify the flow through the regurgitant orifice.

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： A three dimensional ultrasound imaging device, having an interpolator that creates up sampled ultrasound image information from a three dimensional ultrasound image information using interpolation; and a memory that stores at least one of the three dimensional ultrasound image information and the up sampled ultrasound image information. The three dimensional ultrasound imaging device can have a probe that sends ultrasound waves, gathers reflected ultrasound waves and creates ultrasound information and a processor that converts the ultrasound information to three dimensional ultrasound image information. The ultrasound imaging device may also have a display that displays the up sampled image information. The three dimensional ultrasound imaging device may use at least one of 2 image to 3 image interpolation, 2 image to 4 image interpolation, 3 image to 4 image interpolation and 3 image to 5 image interpolation. The three dimensional ultrasound imaging device may use two dimensional solids and three dimensional volumes. The three dimensional ultrasound imaging device may also create up sampled ultrasound image information that has a greater number of frames, a greater number of three-dimensional frames, a greater number of two-dimensional volumes, a greater number of three dimensional volumes and a larger amount of ultrasound information.

摘要： A three-dimensional ultrasound imaging system color user interface generates a volumetrically-rendered ultrasound image. The ultrasound image is manipulable using three-dimensional image compositing functions. The interface presents to the user three-dimensional image controls for controlling the ultrasound image. The three-dimensional image controls have an operational similarity to two-dimensional image controls for controlling a two-dimensional ultrasound image. The interface further relates the three-dimensional ultrasound image controls to the plurality of three-dimensional image compositing functions for manipulating the ultrasound images. Additionally, the interface presents to the user a three-dimensional color image control for controllably manipulating the ultrasound image using three-dimensional image using compositing functions such as a color flow mapping function, a color flow overlay function for mapping fluid flow direction, a depth-based velocity visualization color mapping function; and an absolute velocity representation function for mapping absolute fluid flow velocity relating to said ultrasound object.
