摘要
为获得更清晰的图像检测效果,在超声波波动传播原理的基础上,采用超声阵列检测方法设计超声层析成像(CT)系统。将射线追踪算法引入到层析成像中,基于SIRT重建算法,实现速度重建。通过数值仿真表明:层析成像效果得到明显改善。
In order to make more clear image detection, the ultrasonic wave computed tomography system is designed by using the ultrasonic array detection method based on the ultrasonic wave propagation principle. Based on the SIRT reconstruction algorithm,introducing the ray tracing algorithm into the tomography, the speed of reconstruction is implemented.The numerical simulation results show that the effectiveness of tomography is significantly improved.
