| 摘 要： | 为了解决介入人体腔道诊疗器件的定位问题,提出了一种利用永磁磁场解析表达式组建方程来反推位置的方法.由诊疗器件和永磁体的空间关系模型,确定了未知量的数目.在方程组个数不足时,使用平移永磁体来增加方程组个数,使得两者相等.约束方程组是一组多元非线性方程,进行了数值求解,并和预期位置进行了比较,结果发现该定位方法是切实可行的.

| Abstract: | Equations set based on analytic equation was presented to determine the position of device intervening body cavity to diagnose disease. The number of unknown variables was got from the space relationship model of device and permanent magnetism. Transition of permanent magnet was used to add the number of equations and make them be equal. Numerical method was used to resolve onstraint equations set with multi-variables and non-linearity. Comparison between the result of calculation and expected position demonstrated that this method was feasible. |
