1. A treatment system, comprising:
a visualization sensor configured to be positioned over a tissue site, the visualization sensor configured to collect magnetic induction tomography video data of the tissue site;
an output configured to provide a first alert; and
a controller in communication with both the visualization sensor and the output, the controller configured to:
amplify the video data by Eulerian video magnification;
determine a treatment parameter from the amplified video data, wherein the treatment parameter is derived from a red-delta value and changes in pulse motion indicative of blood flow to the tissue site;
cause the output to provide the first alert in response to determining that the treatment parameter differs from a threshold;
identify areas of skin tension in the tissue site from the amplified video data;
identify Langer's Lines in the tissue site from the identified areas of skin tension; and
identify an intended incision site and wherein the controller is configured to provide a second alert in response to determining that an intended incision site is not aligned with the Langer's Lines.
