A fast continuous rotating ultrasound scan-head transducer was used to perform three-dimensional (3-D) echocardiography with 2-D images acquired during a single cardiac cycle. The 3-D images were reconstructed by interpolating 2-D data acquired with the probe. Two experiments were carried out to validate the image reconstructions. A dynamic cardiac phantom was used as a known reference to compare the minimal and maximal volumes estimated manually on the reconstructed 3-D images. The left ventricle (LV) volume of 30 healthy volunteers also were estimated using a semiautomatic ellipse approach and compared to measurements obtained with standard 2-D examination. Results showed a good agreement between 3-D and reference measurements.
使用快速连续旋转超声扫描头换能器进行三维(3-D)超声心动图检查,在单个心动周期内采集二维图像。通过对探头采集的二维数据进行插值来重建三维图像。进行了两项实验以验证图像重建。使用动态心脏模型作为已知参考,比较在重建的三维图像上手动估计的最小和最大体积。还使用半自动椭圆法估计了30名健康志愿者的左心室(LV)体积,并与标准二维检查获得的测量值进行比较。结果表明三维测量与参考测量之间具有良好的一致性。
