摘　　要：为了评价超声的近、远场及超声深度对三维重建容量测定准确性的影响，我们对１０个球状体在超声的近场和远场进行了三维重建并对１０个椭圆体在超声的１２ｃｍ、１５ｃｍ两个不同超声深度进行三维重建、测定其容量。结果显示，近场和远场所测容量，１２ｃｍ、１５ｃｍ两种深度所测容量高度一致（Ｐ＞０．５）。作者认为，三维超声对容量所测值不受超声近场、远场及超声深度的影响。This study was designed to estimate the influence of echo depth and near and far echo square on the quantitative measurements of 10 ball shaped and 10 ellipsoid shaped phantoms were determined by threedimensional echocardiography in depth at 12cm and 15cm,near and far echo squares.The results revealed that three-dimensional echocardiography was an accurate method for volume computation; It doesn't effect by the echo depth and echo square either near or far.
