Introduction: Click to view
Radiofrequency ablation technology has a wide range of applications in the field of interventional medicine and is currently used for the treatment of tumors in tissues such as the brain, lungs, breasts, liver, kidneys, prostate, bones, etc. The basic principle involves using high-frequency alternating electromagnetic waves (350kHz-500 kHz) to introduce them into the tissue through the treatment electrode, which then forms a circuit via the dispersive electrode. The charged ions in the tissue around the electrode needle oscillate under the influence of the current, generating bioheat. When the local temperature exceeds 45°C-50°C, proteins within normal cells denature, the bilayer lipid membrane dissolves, and the cell membrane ruptures. At the same time, water loss occurs both inside and outside the cells, leading to coagulative necrosis of the tissue. The radiofrequency treatment target tissue modeling and model analysis system presented in this project is a research tool for minimally invasive radiofrequency therapy, providing clinical researchers with more convenient and efficient methods for analyzing target tissue models. Systematically digitize the treatment data of target tissues, and perform data modeling on the target tissues based on the relationships between energy, impedance, and temperature to derive the optimal radiofrequency energy emission scheme for the target tissues.
