Microwave ablation uses dielectric hysteresis to produce direct volume heating of tissue. Microwaves are capable of propagating through many tissue types, even those with high impedance such as lung or bone, with less susceptibility to "heat-sink" effects along vessels. Microwaves are highly conducive to the use of multiple applicators, showing the synergy seen with other energies, but also the potential capability for phasing of the electromagnetic field. As a result, larger, more customizable ablation zones may be created in less time. Although multiple microwave ablation systems are currently available, further study and continued development are needed.
微波消融利用介电滞后产生组织的直接体积加热。微波能够穿透多种组织类型，即使是肺或骨等阻抗较高的组织也能穿透，并且对血管周围的“热沉”效应的敏感性较低。微波非常适合使用多个施源器，显示出与其他能量一样的协同作用，但也有可能对电磁场进行分相。因此，可以在更短的时间内创建更大、更可定制的消融区。尽管目前有多种微波消融系统，但仍需要进一步研究和持续开发。
