Ultrasound diagnosis of cardiac function using cardiac model ventricular segmentation with user control

摘要

To provide users with a simple automated tool for delineating the location of an acceptable heart chamber border.SOLUTION: 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, and the clinicians can create repeatably-drawn borders and exchange the control value for use by others to obtain the same results.SELECTED DRAWING: Figure 5b
