心脏具有复杂的结构,而且不断地收缩与舒张,近10多年来为了对它实现三维重建,学者们对多种三维超声技术做了许多探讨。三维超声心动图是从多个不同角度,不同部位获取心脏、大血管的很多二维切面,然后根据所获得的资料重新显示其立体图像的一种方法。在静息三维基础上加上时间因 The heart has a complex structure, and continuous contraction and relaxation, in recent 10 years to achieve it three-dimensional reconstruction, scholars have done a lot of discussion on a variety of three-dimensional ultrasound technology. Three-dimensional echocardiography is a method of obtaining a large number of two-dimensional sections of the heart and large blood vessels from a plurality of different angles and locations and then redisplaying the three-dimensional images based on the obtained data. Resting on the basis of three-dimensional plus the time factor
