%X 在针对头部肿瘤的线圈式磁感应肿瘤治疗设备设计中,为了提高治疗磁场的强度与均匀度,需要对传统的圆形同轴线圈进行改进。根据临床需求和理论分析,采用D形线圈设计,并通过软件仿真与实际测量加以评估。结果表明:在相同条件下D形线圈与圆形线圈相比其中心磁场强度提高了约5.9%,有效治疗空间增加了约4.6%,设备性能有了一定的提高。线圈电感值的仿真与实际测量结果均符合设备要求。<br>Abstract：A D-shaped coil improved the magnetic intensity and magnetic field uniformity over a circular coil for tumors in the head. The coil was designed using computer simulations and evaluated in trials with the center magnetic field intensity increased by 5.9%, and the valid treatment space increased by 4.6%. The coil also meets the design requirements.
