Abstract

Microwave thermal ablation is under investigation for minimally invasive treatments. In the cases of small targets, such as adrenal glands, microwave thermal ablation is a valuable alternative to the traditional and more invasive treatments (e.g. surgical procedures, pharmaceutical therapies). In this work, ablation treatments are carried out on ex-vivo liver samples using a custom developed microwave ablation applicator for ablation of small targets. Ablation zones achieved with different treatment settings are analysed. The power and time settings suitable to achieve a small and well controlled ablation zone, are evaluated. Moreover, the temperature increase in different regions of the area under treatment is assessed.
牛离体肝脏有效消融区域的实验评价
微波热消融正在研究用于微创治疗。在小目标的情况下,如肾上腺,微波热消融是一个有价值的替代传统的和更具侵入性的治疗(如外科手术,药物治疗)。在这项工作中,使用定制开发的微波消融应用器对离体肝脏样本进行消融治疗,用于小目标的消融。分析了不同处理条件下的消融区。评估了适合实现小而可控烧蚀区的功率和时间设置。此外,还对处理区域不同区域的温升进行了评估。
