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 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 of the volumetric object. The volume of the graphical model 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, and the quantified measures.

摘要： An autostereoscopic display 101, which provides a depth perception by providing a viewer's left and right eyes (104a, 104b) with two slightly different perspectives of an image to be displayed, is provided for ultrasound guided interventions with a surgical instrument (103). The surgeon watches displayed ultrasound data (102), rendered for at least two views. The plane at which those views (L, R) intersect is adjusted to correspond exactly with the tracked three-dimensional position within a displayed scene of the surgical instrument (103), which position can be extracted from the three-dimensional ultrasound data by means of, for example, 3D object recognition. Thus, the point of reconstruction of the image presented to the viewer can be dynamically adjusted to correspond with the position of the surgical instrument on which the surgeon's eyes are presumed to be focused.

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. The appearance of the invasive device (30) in the three dimensional ultrasonic image is enhanced to be more readily observable by a clinician. The enhancement is produced by transmitting a greater ultrasonic beam density in a subvolumetric region including the invasive device (30) than in the surrounding portion of the volumetric region (120). The beam density may be uniformly high in the subvolumetric region and uniformly low in the surrounding region, or may taper from a relatively high beam density around the invasive device (30) to a minimum beam density at distances removed from the invasive device (30).

摘要： 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.

摘要： 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.

摘要： 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.

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. The invasive medical device (30) is shown in a detailed ultrasonic image and the balance of the volumetric region (120) in which the device is located is shown in a wide field of view. The detailed and wide fields of view may be displayed separately or overlapping in spatial alignment on an image display (18). The wide field of view may be shown in two or three dimensions. A quantified display may be shown together with the wide and detailed anatomical displays. The detailed view may also be shown in an enlarged or zoomed format.
