Abstract

Time-response thermography after the application of a mild cold shock is considered a valuable diagnostic tool for breast tumor identification. The concept of this work is to estimate the depth of a malignant tumor based on the time-varying thermographic images after the applied cold shock. Specifically, the heat diffusion model is considered and a thorough numerical analysis reveals the significant temperature variation dependence to a malignant tumor existence. Then, the time-varying curves are approximated utilizing the powerful generalized pencil-of-function method, which leads to the robust extraction of the thermal time constant. The sensitivity of the latter is exceptional considering the detection of the tumor, while the deviation from the peak value provides a strong indication in terms of the tumor’s depth.
