MRI offers many advantages over other modalities and its lack of ionizing radiation is important for children, but can be limited by the radio-frequency (RF) coils available. This work calculates Specific Absorption Rate (SAR) and homogeneity of the RF transmit field (B1+) when imaging ... 詳細を見る
现在 COMSOL Multiphysics® 中对时域问题的处理大多数通过离散时间来处理，比如微波炉中加热一杯水，杯壁由两半不同介电常数的玻璃组成，杯子在托盘带动下旋转，对杯子中的水进行受热分析。传统的解法是将要分析的过程离散为一定步长的时间点，每算完一个时间点将杯子旋转一定的角度，然后在求解器中设置此次计算结果作为下一个时间点的初值。如果时间步长足够短，便可以模拟水的受热情况。这种做法的不足之处是需要调用 MATLAB 联合求解，计算时间较长。而且还有一个问题是在不同的时间点，由于场分布不同，杯子的位置不同，COMSOL 中剖分的网格应该是不同的 ... 詳細を見る
