The enhanced spin polarization produced by optical pumping of gaseous rubidium/xenon samples has made possible a number of recent experiments in nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI). Here we report MRI of laser-polarized xenon in the solid phase at low temperature. Due to the high xenon density in the solid phase and the enhanced spin polarization, it is possible to achieve high intensity and spatial resolution of the image. Signals were observed from xenon films solidified onto the glass container walls and not from an enclosed chili pepper.
通过对气态铷/氙样品进行光抽运产生的增强自旋极化，使得最近在核磁共振（NMR）光谱学和磁共振成像（MRI）方面开展了多项实验成为可能。在此，我们报告了低温下固相激光极化氙的MRI情况。由于固相中氙的高密度以及增强的自旋极化，有可能实现图像的高强度和空间分辨率。从凝固在玻璃容器壁上的氙膜中观察到了信号，而不是从封闭的辣椒中观察到信号。
