Abstract: The invention provides a method for determining a confidence value for an image segmentation. The method includes obtaining an image, wherein the image comprises a view of an anatomical structure and a model of the anatomical structure is obtained, wherein the model comprises a plurality of nodes. The image is processed to generate a plurality of image segmentation outputs, wherein each image segmentation output comprises a set of values for the view, wherein each value of the set of values is associated with a node of the plurality of nodes of the model. For each node of the model, a confidence value is determined based on the plurality of values corresponding to the node. A confidence map of the anatomical structure is generated based on the confidence value of each node.

Abstract: An ultrasonic imaging system produces more diagnostic cardiac images of the left ventricle by plotting the longitudinal medial axis of the chamber between the apex and mitral valve plane as a curved line evenly spaced between the opposite walls of the myocardium. Transverse image planes are positioned orthogonal to the curved medial axis with control points positioned in the short axis view on lines evenly spaced around and emanating from the medial axis. If the short axis view is of an oval shaped chamber the transverse image is stretched to give the heart a more rounded appearance resulting in better positioning of editing control points.

Abstract: An ultrasound imaging system includes a processor circuit in communication with an ultrasound probe. The processor circuit receives, from the ultrasound probe, ultrasound data representative of an ultrasound beam imaging an anatomical structure. The processor circuit determines, based on the ultrasound data, a measured boundary of the anatomical structure. The measured boundary includes multiple locations. The processor circuit determines correction vectors corresponding to the locations of the measured boundary. A magnitude of a respective correction vector is based on a depth of a corresponding location relative to the ultrasound probe and/or an orientation of the measured boundary at the corresponding location relative to the ultrasound beam. The processor circuit applies the correction vectors to the locations of the measured boundary to determine a corrected boundary. The processor circuit outputs, to a display, an ultrasound image based on the ultrasound data.

Abstract: An ultrasonic diagnostic imaging system has a user control by which a user positions the user's selection of a heart chamber border in relation to two myocardial boundaries identified by a deformable heart model. The user's border is positioned by a single degree of freedom control which positions the border as a function of a single user-determined value. This overcomes the vagaries of machine-drawn borders and their mixed acceptance by clinicians, who can now create repeatably-drawn borders and exchange the control value for use by others to obtain the same results.

Abstract: An ultrasonic diagnostic imaging system and method enable the automatic acquisition of standard view planes of the heart in real time, such as the AP4, AP3, and AP2 views. A 3D image of the heart is acquired and the processed in conjunction with a geometrical heart model. The heart model is fitted to the heart in its acquired pose to segment the desired image planes from the 3D image data. During successive image acquisition intervals the image planes are tracked through successive image data as a multi-plane system to update a display of the multiple images. The successive image acquisitions can be volume image acquisitions or multi-plane acquisitions of just the tracked image planes during each acquisition interval.

Abstract: 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.
