To be able to describe more precisely the behavior of a real-time 3-D ultrasound system with either a dense array or various sparse designs, experimental data from a 2-D fully connected array prototype with 50 x 50 elements have been collected. The data have been processed off line to form synthetic aperture 3-D volume images. Simulated and experimental results are compared and show good correlation. The performance of the best sparse designs, all thinned to more than 50%, offer performances comparable to a dense array.
为了能够更精确地描述具有密集阵列或各种稀疏设计的实时三维超声系统的性能，我们收集了来自一个具有50×50个元件的二维全连接阵列原型的实验数据。这些数据已离线处理以形成合成孔径三维体积图像。将模拟结果与实验结果进行比较，结果显示出良好的相关性。所有稀疏程度超过50%的最佳稀疏设计的性能与密集阵列相当。
