摘要： An ultrasonic imaging system produces a sequence of images of the heart during a cardiac cycle. The images are analyzed to determine the motion, displacement, or change in size of segments of the myocardium. In a preferred embodiment the values determined are radial, longitudinal, or circumferential myocardial strain values. The displacement of the myocardial segments may be tracked during the cardiac cycle by speckle tracking or border detection. The motion, displacement, or change in size values for the segments are analyzed to produce a recruitment curve and anatomical display showing the relative times of recruitment of the different segments in the contractile and relaxation motion of the heart. Participation in and achievement of full recruitment may be determined by comparison against an initial recruitment threshold criterion and against a predetermine maximal recruitment milestone level.

摘要： An ultrasonic diagnostic imaging method and system are described for detecting abnormalities in the synchronicity of heart wall stimulation. Points on opposite sides of a chamber of the heart are identified in a starting ultrasound image, then tracked through at least a portion of the heart cycle. The changing positions of lines extending between pairs of the points are accumulated and displayed in a color kinesis display in which each color depicts the location of a line at a particular point in the cardiac cycle. In an illustrated example the points are tracked through the cardiac cycle by speckle tracking of the speckle pattern of the adjacent myocardial tissue, tracking specific anatomy, or tracking tissue texture.

摘要： An ultrasonic imaging system and method are described for quantification and display of myocardial wall thickening. The endocardial and epicardial borders in an image sequence are defined over a heart cycle and changes in the distance between the borders are tracked at specified locations around the myocardium over the heart cycle, The changes in distance are presented to the user in a graphical format, preferably together with another measure of the cardiac cycle such as chamber volume variation, ejection fraction, or the ECG waveform. The changes in the distance of chord lengths across the myocardium provide a direct indication of wall thickness variation at the specified locations. Preferably the tracking of the specified locations over the heart cycle is done by speckle tracking. The inventive technique can also represent strain at the specified locations of the myocardium.

摘要： The present invention relates to an imaging system for displaying a structure of temporally changing configuration. The imaging system comprises a display rendering means which processes the image data representative of the structure, renders a display representative of the structure and a presents a display panel of key data indicia which relates to the key data of the structure. The data indicia is targeted within a two stage process, which first causes the relevant computer generated trace image related to the data indicium to be superposed upon the relevant ultrasound image. The second stage provides the option of selecting the data indicium to further reveal information about the structure. Such an interaction provides all the data related to a key measurement and not just the end result, without cluttering the display images by displaying all the image data simultaneously.

摘要： A diagnostic imaging method and ultrasound system are described for detecting abnormalities of the left ventricle of the heart. A sequence of images including the mitral valve is acquired and processed to identify the location of the mitral valve in each of the images in the sequence. A graphic is displayed with the images depicting the location of the mitral valve in the current image and in each of the preceding images of the sequence. Preferably the mitral valve location is identified by automatic detection of the mitral valve plane in each of the images. A desirable graphic color-codes each of the successively different mitral valve locations in the graphic. The image and graphic can be viewed in real time to discern the effects of conduction delay and infarction of the left ventricle.

摘要： Quantified measures of a volumetric object in the body can be made ultrasonically by acquiring concurrent biplane images of two different image planes (210, 214) of the object. Corresponding borders of the volumetric object are traced using automatic border detection. The border tracings are used in their planar spatial relationship to compute a graphical model (220) of the volumetric object. The volume of the graphical model (220) may be computed by the rule of disks, and a graphical or numerical display of the changing volume with time displayed. A user interface comprises both real time biplane images, the real time graphical model (220), and the quantified measures.

摘要： A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device (30) in three dimensions. An interventional system (20) is used to operate the invasive medical device (30) and produces spatially-based information relating to the activity of the invasive medical device (30). The spatially-based information from the interventional system (20) is merged into the three dimensional ultrasonic image data to produce a live three dimensional image of the invasive medical device (30) or its activity. In one embodiment the locations where the activity of the invasive medical device (30) is performed is recorded and displayed in the three dimensional ultrasonic image. The three dimensional ultrasonic image may be shown as an anatomical volume rendered image or as a wire frame model (130) of the anatomy. In another embodiment an integrated three dimensional ultrasonic imaging and invasive device system is described.
