Materials and Methods: NTHI was used to observe the morphological changes of 42 lesions in 30 patients with liver cancers before and 1 week after cluster electrode radio frequency ablation.

AIM The hemodynamic changes of ha, PV and tumors in hepatic cancer patients treated by cluster electrode radio frequency ablation were studied with color Doppler flow imaging (CDFI).

This invention relates to a physiological sensor which acquires pre-programmed data from an electrode or an electrode array using Radio Frequency Identification (RFID) technology.
