【Abstract】 The basic principle of a practical analyzing system of dynamic three-dimensional echocardiogram (PASDTDE) is described. It shows the circuit diagram which can automatically digitize the image of two-dimensional echocardiograms in real- time and its image information sampling can be synchronized by ECG triggle. The method of distinguishing the boundary of left ventricle automatically and allgorism of the reconstruction on dynamic three- dimensional image and the calculation of the characteristic parameters of the left-ventricale are discussed respectively. The applied results in clinic are given.更多还原
