Methods and systems for segmentation in echocardiography |
| 摘要 |
Methods and systems for segmentation in echocardiography are provided. One method includes obtaining echocardiographic images and defining a search space within the echocardiographic images using a pair of one-dimensional (1D) profiles. The method also includes using an energy based function constrained by non-local temporal priors within the defined search space to automatically segment a contour of a cardiac structure with the 1D profiles. |

1. A method for automatic segmentation of a cardiac structure, comprising:
obtaining echocardiographic images; defining a search space within the echocardiographic images using a pair of one-dimensional (1D) profiles; and using an energy based function constrained by non-local temporal priors within the defined search space to automatically segment a contour of the cardiac structure with the 1D profiles, wherein using the energy based function comprises penalizing a spatial smoothness of the acceleration of the 1D profiles. |
