CIRCULATION SYSTEM EVALUATION

Methods and systems are provided for evaluating a region of interest in a circulatory system of a subject. The method comprises: obtaining (210) a time sequence of ultrasound image frames of the region of interest; obtaining (220, 320) one or more trained models; inputting (250, 350) a time sequence of ultrasound image frames into the one or more trained models; and analyzing (260, 360) a time sequence of ultrasound image frames using the one or more trained models to produce output data characterizing a condition of the region of interest, where the output data characterizes a degree of atherosclerosis or calcification of the region of interest, and where the region of interest is an aortic valve. An associated training method for training one or more models is also provided. 提供了用于评估对象的循环系统中的感兴趣区的方法和系统。所述方法包括：获得(210)所述感兴趣区的超声图像帧的时间序列；获得(220、320)一个或多个经训练的模型；将超声图像帧的时间序列输入(250、350)到所述一个或多个经训练的模型中；并且使用所述一个或多个经训练的模型来分析(260、360)超声图像帧的时间序列，以产生表征所述感兴趣区的状况的输出数据，其中，所述输出数据表征所述感兴趣区的动脉粥样硬化或钙化的程度，并且其中，所述感兴趣区是主动脉瓣。还提供了一种用于
