| | The model establishment and numerical simulation of SAR and the instantaneous temperature distribution for no-wound tumor RF thermotherapy are performed in this paper. The model can correctly represent the attenuation of electromagnetic wave in the biotissue, the variation of blood perfusion with temperature and lower blood perfusion of the tumor tissue are fully considered in the model, the simulation results are close to the clinic practice with these measures. Detailed analyses and discussion... | | 本文针对非侵入性射频热疗的SAR场及瞬态温度分布进行建模和数值模拟计算。采用了能正确反映电磁波在生物组织中衰减的电磁场模型。在温度场模拟中考虑了血液灌流项随组织温度变化和肿瘤区低血液灌流的特点,这些措施使模拟计算结果更加符合临床实际。还对射频热疗电磁能量分布和温度分布的特点及其影响因素等作了细致的分析和讨论。 | | 文摘来源 | | In this paper are reported the model establishment and numerical simulation of specific absorption rate(SAR) and the unsteady temperature distribution for the non-invasive tumor RF thermotherapy.
