Research on a laser ultrasonic visualization detection method for human skin tumors based on pearson correlation coefficient

•This study explores the feasibility of using laser generated ultrasonic wave to detect human skin tumors.•The pearson correlation coefficient method is used to evaluate the skin tumor-induced waveform variation and thus position the skin tumor accurately.•The correlation coefficient method is a feasible tool detecting and characterizing tumor in human skin. Tumor as a kind of skin cancer is a serious threat to human health, In order to diagnose and treat skin diseases, many organizations are studying methods to confirm and monitor skin diseases by detecting the characteristics of human skin. This study explores the feasibility of using laser generated ultrasonic wave to detect human skin tumors, the pearson correlation coefficient method is used to evaluate the skin tumor-induced waveform variation and thus position the skin tumor accurately. The simulation results show that the correlation coefficient method is a feasible tool detecting and characterizing tumor in human skin.
