Zusammenfassung:	An instrument (14) is suitable for treatment of lung tumors and other tissues and a respective apparatus (15) detects the correct positioning of instrument (14) and its two electrodes (19, 20) in a suitable target tissue by observation of two parameters (G1, G2) and particularly their time-dependent change. If the change (V1, V2) of the two parameters (G1, G2) exceeds defined thresholds (S1, S2) respectively, a contact between the instrument and the tissue to be treated and also the positioning of the instrument in a desired position can be derived therefrom. Accordingly, the present invention remarkably contributes to increasing treatment safety. 기구(14)는 폐 종양들 및 다른 조직들의 치료에 적합하고 각각의 장치(15)는 2개의 파라미터들(G1, G2) 및 특히 이들의 시간-종속 변화를 관찰하여 적합한 목표 조직에서 기구(14) 및 그것의 2개의 전극들(19, 20)의 정확한 포지셔닝을 검출한다. 만약 2개의 파라미터들(G1, G2)의 변화(V1, V2)가 규정된 임계값들(S1, S2)을 각각 초과하면, 기구와 치료될 조직 간의 접촉 및 또한 원하는 위치에서의 기구의 포지셔닝이 그것으로부터 도출될 수 있다. 따라서, 본 발명은 치료 안정성을 증가시키는데 현저하게 기여한다.
