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。
- Abstract:
- In order to make more clear image detection,the ultrasonic wave computed tomography system is designed by us-ing the ultrasonic array detection method based on the ultrasonic wave propagation principle.Based on the SIRT reconstruc-tion algorithm,introducing the ray tracing algorithm into the tomography,the speed of reconstruction is implemented.The nu-merical simulation results show that the effectiveness of tomography is significantly improved
