The dominant signature of thermal breast images is vascular heat. We analyzed dynamic thermograms as a response to external stimuli. The vascular response to temperature stimulus is affected by vasomodulation. We are using the Brazilian visual lab mastology data set. The recorded data is analyzed by converting the diffusive heat propagation into a virtual wave and identifying the reflection using component analysis. We identified two classes of images: 1. The dominant one is a reflection at the same polarity as the applied temperature stimulus (vasoconstriction). 2. A second reflection at twice the depth and reverse polarity (vascular reflection).
