ajst-12250	Yao, Xin	Research and Design of High-precision Voltage Sampling Circuit for Tumor Radiofrequency Ablation Medical Instrument	2023	4	.pdf	application/pdf	1486	76	56	China Abstract: Radiofrequency ablation is a minimally invasive procedure in which tiny radiofrequency electrodes are implanted into the diseased tissue under the guidance of medical imaging (X-ray imager, CT or ultrasound), and neutral electrodes are attached to the skin of the body to carry out radiofrequency ablation, which is carried out by forming a circuit through the human body to the diseased tissue. 2. Hardware Design Since tumor radiofrequency ablation uses a standard sine wave with a fixed frequency, its waveform contains very few harmonic components, so the following relationship exists between its RMS and peak values Vrms = 0.707×Vpeak Therefore, the RMS value of the voltage can be obtained by measuring its peak value and thus the energy output to the lesion can be obtained.	cache/ajst-12250.pdf	txt/ajst-12250.txt
