Definitions

  • the present invention relates to a device and a method for displaying tissue changes in thermotherapy with at least one first emitter for emitting a test light of a predetermined wavelength, at least one detection device being arranged at a constant, predetermined and variable distance from the first emitter, and the detector device is designed to receive and emit light.
  • the device according to the invention for displaying tissue changes in thermotherapy comprises at least one second emitter for the therapeutic change in the temperature of a tissue region, it being possible to generate structural changes in the tissue.
  • the change in temperature can be generated by means of a hot liquid or also by means of microwaves.
  • the use of ultrasound or of refrigeration generators is also possible in order to achieve the therapeutic temperature change.
  • the detection device 16 is pierced into the tissue at a defined distance or a defined geometry from the emitter 12a.

Abstract

L'invention concerne un dispositif (10) et un procédé pour représenter des modifications tissulaires lors d'une thermothérapie. Ce dispositif (10) comprend au moins un premier émetteur (12a) servant à émettre une lumière test d'une longueur d'onde prédéterminée, et un deuxième émetteur (12b) servant à modifier, à des fins thérapeutiques, la température d'une zone tissulaire. Il en résulte des modifications de la structure du tissu. Au moins un dispositif de détection (16) est placé à une distance constante, prédéterminée et modifiable, de l'émetteur (12a).
