An alternative approach, magnetic resonance force microscopy (MRFM), uses force detection to overcome the sensitivity limitations of conventional MRI. Here, we show that the two-dimensional imaging of nuclear spins can be extended to a spatial resolution better than 100 nm using MRFM. The imaging...
答:核磁共振(Nuclear Magnetic Resonance即NMR)是处于静磁场中的原子核在另一交变电磁场作用下发生的物理现象。通常人们所说的核磁共振指的是利用核磁共振现象获取分子结构、人体内部结构信息的技术。 并不是所有原子核都能产生这种现象,原子核能产生核磁共振现象是因为具有核自旋。原子核自旋产生磁矩,当核磁矩处于静止外...
核磁共振成像 (NMRI,Nuclear Magnetic Resonance Imaging),也称磁共振成像(MRI,Magnetic Resonance Imaging),是一种核物理现象,MRI的物理基础是核磁共振(NMR,Nuclear Magnetic Resonance)理论。 所谓NMR,是指与物质磁性和磁场相关的共振现象。也可以说,它是低能量电磁波,即射频波与既有角动量又有磁矩的核系统在外磁场...
