A New Method of Localized Microwave Scanning Magnetic Fieldfor Electron Paramagnetic Resonance Imaging

报导了电子顺磁共振成像的微波局域场方法．在改进的自制小型顺磁共振谱仪上，给出了测试样品ＤＰＰＨ的二维电子自旋密度分布图像．使用退卷积算法和反向滤波图像处理技术，提高了分辨率．

A new method of localized microwave scanning field for two-dimensional election paramagnetic resonance (EPR) imaging is described. A two-dimensional EPR image corresponding to electronspin density distribution of the DPPH tested sample was obtained using a (self-made) marginal--oscillating self--detecting microwave frequency electron paramagnetic resonance spectrometer.
