1. A method for ascertaining, and responding to, a tissue characteristic of a surface region of patient tissue comprising the steps of:

  • a) obtaining a scanned beam device adapted to transmit a beam of sensing radiation to impinge on the surface region, to collect radiation returned from the surface region which has been impinged with the transmitted beam of sensing radiation, and to measure the reflectance of the surface region from the collected radiation;

    b) using the scanned beam device to transmit a beam of sensing radiation to impinge on the surface region;

    c) using the scanned beam device to measure the reflectance of the surface region from the collected radiation returned from the surface region;

    d) determining the tissue characteristic of the surface region from the measured reflectance, wherein the tissue characteristic is different from but related to the measured reflectance; and

    e) providing an indication of the determined tissue characteristic, wherein the indication is other than a displayed image of the surface region.
