对于单元发、阵接收的模型，采用反射回波的包络作为投影，按滤波后投影算法（ＦＢＰ法）进行重建，得到物体内某一截面的重建像，然后调整接收阵的位置，获取多层截面的投影并重建成像，运用体绘制法（ＶｏｌｕｍｅＲｅｎｄｅｒｉｎｇＩｍａｇｉｎｇ）绘制了三维像，图像效果不好，分辨率不高。针对这一问题，文中应用了电子延迟方法处理接收信号，即对接收阵各阵元接收到的回波信号依照散射点相对接收阵的空间位置关系进行一定时间的延迟，利用此种方法重复上述步骤经过计算机模拟实验后得到的图像质量明显改善，成像分辨率得到提高。
For the unit hair, the array receives the model, using the reflected echo envelope as a projection, according to the filtered projection algorithm (FBP method) to reconstruct, to get the reconstructed image of a cross-section of the object, and then adjust the position of the receiving array, access to more Layer projection and reconstruction of the image, the use of volume rendering (VolumeRenderingImaging) to draw a three-dimensional image, the image is not good, the resolution is not high. In order to solve this problem, we apply the electronic delay method to process the received signal. That is to say, the echo signal received by each array element of the receiving array is delayed by a certain time according to the spatial position of the scattering point relative to the receiving array. In this way, The image obtained by the step after computer simulation is obviously improved, and the imaging resolution is improved.
