为了解决介入式诊疗器件的定位问题,提出了利用电磁定位系统的设计方法。根据三维电磁定位的原理,推导出了相应的数学模型,介绍了系统软硬件的具体实现方法,给出了实验结果并对结果进行了分析。实验结果表明,该方法具有可行性,在3～30 cm的范围内定位误差在3 cm以内,并且具有较好的抗干扰能力。
In order to solve the positioning problem of interventional therapeutic device, a design method using electromagnetic positioning system is proposed. According to the principle of three-dimensional electromagnetic positioning, the corresponding mathematical model is deduced, and the concrete realization method of system hardware and software is introduced. The experimental results are given and the results are analyzed. The experimental results show that this method is feasible, with the positioning error within 3 cm in the range of 3 ~ 30 cm, and has good anti-interference ability.
