Feasibility study of blood vessel detection in fat using high-frequency current

In this study, we proposed a low-cost and simplified method for detecting blood vessels in fat using high-frequency current during surgery. Conventional methods for detecting blood vessels are not often used in surgery because they are complex systems to detect blood vessels for surgeon. In this paper, we calculated the real and imaginary parts of impedance between two electrodes inside the presence and absence of blood vessel in the fat in kHz band. Based on the results, we could find the possibility of blood vessel detection in the fat by impedance change.
