介绍了一种电子自旋共振成像系统，该系统能够在几分钟内获得分辨率为∼10×10×30 μm的三维图像。这台电子自旋共振显微镜采用商用连续波电子自旋共振光谱仪，工作频率为9.1GHz，配合微型成像探头(谐振器+梯度线圈)、梯度电流驱动器和控制软件。该系统可以通过调制场梯度法、投影重建法或两者相结合的方法获取小尺寸(∼1.5×1.5×0.25 mm)样品的图像。对调制场梯度法在二维(2D)和三维成像中的分辨率作了简要的讨论。文中提供了各种系统组件的详细说明，以及演示系统功能的2D和3D图像的几个示例。
An electron spin resonance (ESR) imaging system, capable of acquiring three-dimensional (3D) images with a resolution of ∼10×10×30 μm in a few minutes of acquisition, is presented. This ESR microscope employs a commercial continuous wave ESR spectrometer, working at 9.1 GHz, in conjunction with a miniature imaging probe (resonator+gradient coils), gradient current drivers, and control software. The system can acquire the image of a small (∼1.5×1.5×0.25 mm) sample either by the modulated field gradient method, the projection reconstruction method, or by a combination of the two. A short discussion regarding the resolution of the modulated field gradient method in two-dimensional (2D) and 3D imaging is given. Detailed descriptions of the various system components are provided, along with several examples of 2D and 3D images that demonstrate the capabilities of the system.
