An alternating magnetic field created inside the MRI's tube excites hydrogen atoms in the body's tissues, making them emit radio waves.

在磁共振扫描仪管道内部产生的交互式磁场会激发人体组织内的氢原子，使氢原子发射出无线电波。

After 100 days, they thawed the organs with an alternating magnetic field, which caused the nanoparticles to oscillate and evenly warm the tissue.

100 天后，他们用交变磁场解冻器官，这导致纳米粒子振荡并均匀地加热组织。
