User-controlled cardiac model Ultrasonography of cardiac function using ventricular segmentation

摘要

PROBLEM TO BE SOLVED: To provide a user with a simple automation tool for describing the position of an acceptable ventricular boundary. An ultrasonic diagnostic imaging system has a user control unit that positions a user selection of a ventricular boundary with respect to two myocardial boundaries identified by a deformable cardiac model. User boundaries are positioned by a single degree of freedom control that positions the boundaries as a function of a single user-determined value. This overcomes changes in machine-drawn boundaries, and their mixed acceptance by clinicians, creates repeatably drawn boundaries, and exchanges control values for other uses to achieve the same result. obtain.
