【摘要】 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AlNiCo₅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。更多还原

【Abstract】 -In this paper, a new method of fast data acquisition with rotational scanning for 8-D magnetic field imaging by CT technique is introduced. In comparison with linear scanning, the method increases the speed of data acquisitin. B usiush oyitg new method, a measurement system has been set up and images of magnetic field leaking from a pair columnar AINiCo₅ magnet are performed and reconstructed. The result shows that with this syme tiesth, maging is fast, accurate and clear.更多还原
