为了全面评价超声三维图像重建法测定容积的准确性,我们对54个球状体、11个椭圆体、13个不规则体进行了研究,同时和两维超声所测值进行了比较.结果表明:兰维测定容量和实测值高度相关.球状体、椭圆体、不规则体的相关系数分别为0.998、0.996和0. 998,且与实测值相比无显著差异(P>0.05).两维的相关系数分别为0.997,0.994和0.96,但对球体和不规则体所测值与实则值相比差异显著(P<0.005),仅对椭圆体所测值与实测值差异不明显(P>0.5).作者认为,三维图像重建法对容量的测定较为准确,特别对球体和不规则体的测定优于两维超声心动图.

The purpose of this study was to compare the feasibility of in vitiro quantitative measurement of phantoms with varFing size and shape by three-dimensional echocardiography(3DE) and tw dimensional echicardlography(2DE).The volumes of 78 wate-filed ballon phantoms of varying size and shape(54 ball shapes,11 ellipsoids,13 irregular shapes)wese calculated by 2DE and 3DE.Results : Reconstructed cavityr Volumes hy 3DE were well in accordance with actual values(r=0.998,0.996,0.998,respectively). Three waa no significant difference between them(P>0.5) The volumes by 2DE also correlated well with actual values (r=0.977,0.994,0.960 rspectively).dimensional echocardiography privides an accurate method for volume computation .It is superior to the 2DE,especiakiy in measuring a model with ball and irregular shape.
