20080294048 | Ultrasonic Diagnosis of Myocardial Synchronization - 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. | 11-27-2008 |
20090009512 | IMAGING SYSTEM - 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. | 01-08-2009 |
20090136109 | ULTRASONIC DIAGNOSIS BY QUANTIFICATION OF MYOCARDIAL PERFORMANCE - An ultrasonic diagnostic imaging system is described which acquires 3D data sets of the heart including the myocardium. The epicardial myocardium in the data sets are identified by automated or A 3D image of the myocardium is produced from the defined surfaces. The 3D image illustrates the wall regions, with quantified measures made for each defined region. | 05-28-2009 |
20100056915 | 3D ECHOCARDIOGRAPHIC SHAPE ANALYSIS - An ultrasound system and method are described for assessing cardiac performance which is particularly useful for diagnosing heart remodeling. A 3D data set of a surface of the heart is acquired and the principal curvatures determined at one or more points of the surface. A curvature metric is produced which is the difference of the two principal curvatures at each point. Metrics produced from the heart surface acquired at systole have been found to correlate strongly with ejection fraction. | 03-04-2010 |
20130165781 | INTEGRATED DISPLAY OF ULTRASOUND IMAGES AND ECG DATA - A display system for ultrasound images and ECG data produces a common display of a cardiac ultrasound image of a given view and ECG traces relevant to that ultrasound view. The ECG traces relate to the heart anatomy seen in the ultrasound image. The user is given the ability to select certain ECG lead signals for display in conjunction with specific views of the heart. ST elevation values for the ECG leads may also be shown to enable the clinician to correlate electrical abnormalities with anatomical abnormalities of the ultrasound image such as abnormal wall motion or thickening. The ST elevation values are displayed on a bullseye chart in association with heart regions related to the leads for which the ST values were detected. | 06-27-2013 |
20130231564 | AUTOMATED THREE DIMENSIONAL AORTIC ROOT MEASUREMENT AND MODELING - An ultrasound system for planning a surgical implantation of a prosthetic aortic valve produces three dimensional images of the aortic root region of a patient. An electronic model of an aortic root is accessed and fitted to the aortic root in a three dimensional ultrasound image. Preferably the aortic root model exhibits closed contour cross-sections which are fitted to the endothelial lining of the aortic root in the ultrasound image. A medial axis of the fitted model is identified and radii measured from the medical axis to the border of the fitted model. The radii are joined to identify a surface forming a mesh model fitted to the aortic root anatomy of the patient. The shape and dimensions of the fitted model may be used to fabricate a custom prosthetic valve for aortic valve replacement. | 09-05-2013 |
