INTERVENTIONAL DEVICE FOR RF ABLATION FOR USE IN RF FIELDS |
摘要 |
A interventional device for RF ablation for use in a RF electrical and/or magnetic field especially of a MR imaging system is disclosed, comprising an ablation catheter which is preferably trackable or can be guided or visualized in the image generated by the MR imaging system by means of a MR micro-coil (102), and which is provided with an ablation electrode (101). The interventional device further comprises a transmission path (103) with line segments (104′, 104″) and transformers (105) therebetween, for connecting the MR micro-coil (102) in a differential mode with a MR receiver (108) and for connecting a RF amplifier (107) in a common mode with the ablation electrode (101) for conveying RF ablation power. |
