Abstract: To automatically control a treatment during which subcutaneous or intracutaneous irradiation by means of electromagnetic treatment radiation and possibly targeted electromagnetic radiation is carried out, the following steps are implemented: acquisition of several successive images l(t) of the treated zone by means of an external sensor (1), which is sensitive to the wavelength or the range of wavelengths of the electromagnetic treatment radiation or of the targeted electromagnetic radiation, the time interval (?) between two successive images [l(t?1); l(t)] being known, detection and localisation in each image l(t) of a light spot p(t) corresponding to the irradiation spot (S) of the electromagnetic treatment radiation or the targeted electromagnetic radiation, calculation for each light spot p(t) of at least one of the following parameters: the energy [eij(t) or Eij(t)] supplied from the power P(t) of the electromagnetic treatment radiation and the time interval (?) between two successive images [l(t?1); l(

Abstract: Device for treatment of a part of a human or animal body, including: treatment dose delivery means enabling treatment doses to be delivered to the human or animal body, mapping means enabling a zone or a volume of the body to be treated to be mapped and spatially defined in a predefined frame of reference and in a form of mapping data, localisation means enabling the instantaneous position of the treatment dose delivery means outlet to be localised in the form of localisation data in the frame of reference, electronic control means, which, are suitable for recording the mapping data of at least one zone or one volume of the body to be treated, acquired with the help of the mapping means, and which, enable a treatment to be controlled by using, during the course of the treatment, at least the mapping data and the localisation data.
