【摘要】 作者通过对不同角度的左心室心尖部沿左室长轴的二维超声图进行边缘检测.将所得不同截面的左心室边缘点按其空间位置重建左心室三维图,从而得出有关的心功能指标。采用人心标本做左心室三维重建实验,得到了左心室的线框图和灰度图显示,由左心室三维图计算出的左心室容积与测量值基本相符。更多还原

【Abstract】 This subject is to reconstruct three-dimensional images of left ventricle by detecting edges of two-dimensional echocardiograms and re-building the special model according to their volume and motion indices which describe cardiac function. We use the excised human hearts to do the experiment of 3-D reconstruction,get the left ventricular 3-D image of wireframe and shades of grey. The volume of left ventricle that we calculate from the 3-D images according with what we measure actually.更多还原
