摘要

介绍了一种在m型超声心动图中检测心肌边界的顺序方法。初始边界估计由互相关检测器获得。然后通过自适应格形式联合过程预测器对其进行改进。另一种方法是利用生理约束来改善心脏收缩期心内膜的检测。提出了一种递归更新相关模板的最小二乘算法，以跟踪相关模板的时间变化。

Myocardial border tracking in M-mode echocardiograms using joint process estimation

A sequential approach to the detection of myocardial borders in M-mode echocardiograms is introduced. Initial border estimates are obtained from a cross-correlation detector. They are then improved by an adaptive lattice-form joint process predictor. Alternatively, a physiological constraint is used to improve the detection of the endocardium during systole. A least squares algorithm is proposed to update recursively the correlation templates in order to track their temporal variations.<>
