A surface coil probehead was worked out for the superconducting 50 mm bore magnet of NMR a high resolution NMR spectrometer with the field strength 8,46 T (145.78 MHz for 31P nuclei) with a 50 mm slot. The requirements were analysed for the surface R.F. coil to obtain the greatest possible single/noise ratio at fixed space selectivity. Real penetration depth of the radio-frequency field into the specimen was estimated. Spectra of liver and abdominal muscle of anesthetized mouse were obtained. The probehead may be applied to obtain high resolution 31P spectra in vivo studies of animal organs.
为一台场强8.46 T（对31P核为145.78 MHz）、带有50 mm狭缝的高分辨率核磁共振光谱仪的50 mm孔径超导磁体制备了一个表面线圈探头。分析了表面射频线圈在固定空间选择性下获得最大可能信噪比的要求。估算了射频场在样品中的实际穿透深度。获得了麻醉小鼠肝脏和腹部肌肉的光谱。该探头可用于在动物器官的体内研究中获取高分辨率的31P光谱。
