Abstract
Calculations of the effect of torso geometry on the extracorporeal magnetic field produced by a simple cardiac source have been carried out. Contrary to the results at present in the literature, it is found that the field solution is stable under perturbations of geometry in the sense that small relative changes in geometry produce comparably small changes in the magnetic field. Thus, simplified torso models may have a wider range of validity and usefulness than was previously thought.
摘要
已对躯干几何形状对简单心脏源产生的体外磁场的影响进行了计算。与目前文献中的结果相反，发现磁场解在几何形状扰动下是稳定的，即几何形状的相对小变化会在磁场中产生相对小的变化。因此，简化的躯干模型可能具有比以前认为的更广泛的有效性和实用性。
