摘　　要：为了检验和评价彩色室壁动态技术跟踪和显示的左室心内膜位移的准确性，我们在２５例患者中同时进行了多平面经食管左室二维超声和ＣＫ技术检查，并利用自制的计算机软件对上述图像进行左室腔体积和ＣＫ色带体积的三维重建，结果显示：左室三维ＣＫ图像不仅可立体显示左室的整体室壁运动状态，而且左室三维重建后的ＣＫ色带体积与三维重建法测量的心搏量高度相关（ｒ＝０．９２，ｐ＜０．００１）。To evaluate the accuracy of Color Kinesis(CK)technique in tracking wall motion,multiplane transesophageal two dimensional echocardiographic and Color Kinesis studies were performed in 25 cases with heart disease.We obtained three dimensional images with a soft ware program.The result showed that left ventricular 3 D CK images could display the entire left ventricular wall motion.There was high correlation between stroke volume(SV) calculated from the left ventricular 3 D images and the volame occupied by the CK band calculated from the left ventricular 3 D CK images(Vc) (r=0 92,p<0 001).It is concluded that Color Kinesis is a reliable technique for quantitative assessment of entire left ventricular wall motion.
