本文介绍采用CT技术重建三维磁场图像的圆扫描数据采集方法。与线性扫描方式相比较,提高了数据采集速度。通过对一对AlNiCo_5圆柱体任一断面上磁场的测量与成像,表明该系统具有成像速度快、清晰精确等优点。
This article describes the use of CT technology to reconstruct three-dimensional magnetic field image scanning data acquisition method. Compared with the linear scanning method, the data acquisition speed is improved. The measurement and imaging of the magnetic field on any cross section of a pair of AlNiCo_5 cylinders indicate that the system has the advantages of fast imaging speed and clearness.
