Ultrasound diagnosis of cardiac performance by single-degree-of-freedom heart chamber segmentation

摘要

The ultrasound diagnostic imaging system has a user controller that allows the user to position a user selection of a heart chamber boundary relative to two machine-drawn heart chamber tracings. The user selected boundary is positioned by a single degree of freedom controller that positions the boundary as a function of one user-determined value. This overcomes variations in machine-drawn boundaries and their acceptance by clinicians, allowing clinicians to generate repeatedly drawn boundaries and control for use by others to achieve the same results The value can be exchanged.
