An apparatus for dynamic imaging of the blood perfusion in skin measures blood flow in human or animal skin non-invasively, by means of processing skin thermographic data. An area of skin is first cooled, the cooling means is removed, and then, using an infra-red detector, thermographic data corresponding to skin temperature is obtained at a number of points on the area of skin over a period of time. For each point an exponential fit equation for the variation with time of the thermographic data is calculated. The coefficients of the exponential fit equation are displayed in graphical map form, and the map can be interpreted to provide information about the blood perfusion rate in the skin. <IMAGE> |
