微波的原理 1. 微波肿瘤消融原理与微波炉一个原理(Microwave for tumor ablation –same principle as microwave oven) 2. 微波引起水分子的运动和振荡-水分子的摩擦产热(IMicrowaves cause movement / oscillation of water molecules –heat generated by friction of those water molecules) 3. 微波炉的能量在内部(Microwave oven –energy deposition inside),消融的能量朝向周边组织(energy deposition towards surrounding tissue) 微波消融的潜在优势(MW Ablation: Potential Advantages) 较大的消融容积:能量穿透深(IBigger ablation = Deeper penetration of energy) 热度高:IHotter = applicator temps. 120 -140°C) 快速的消融时间:Faster ablation time |
