中场强矩形表面线圈结构简单,主要应用于脊柱四肢等。所以研制有一定的实用价值。设计表面线圈主要考虑到此线圈在主磁场中要产生均匀的磁场B1,无大的辐射,有高的品质因素Q,要同主机的阻抗相匹配,在中心频率时共振。1方法一个典型的线圈如图1所示。在线圈中任取一点(ρ,y),假设 Midfield strong rectangular surface coil structure is simple, mainly used in spine and other limbs. Therefore, the development of a certain degree of practical value. Design surface coil mainly consider this coil in the main magnetic field to produce a uniform magnetic field B1, no big radiation, high quality factor Q, to match with the host impedance, resonance at the center frequency. A method A typical coil shown in Figure 1. Take a point in the coil (ρ, y), assuming
