Title (EN) REAL-TIME 3D MICROWAVE MONITORING OF THERMAL THERAPY
(FR) SURVEILLANCE EN TEMPS RÉEL PAR MICRO-ONDES EN 3D D'UNE THÉRAPIE THERMIQUE
Abstract:
(EN) A method for determining a change of temperature of an object. The method may include heating an object and measuring scattering parameters (S-parameters) of scattered microwave electric fields from the object. A distorted Born iterative method may be used to determine a change of a dielectric property of the object based on the measured S-parameters. A change of temperature of the object may be determined based on the change of the dielectric property of the object.
(FR) La présente invention concerne un procédé permettant de déterminer un changement de température d'un objet. Le procédé peut comprendre le chauffage d'un objet et la mesure de paramètres de diffusion (paramètres S) de champs électriques micro-ondes diffusés à partir de l'objet. Un procédé itératif lié à une distorsion peut être utilisé pour déterminer un changement d'une propriété diélectrique de l'objet sur la base des paramètres S mesurés. Un changement de température de l'objet peut être déterminé sur la base du changement de la propriété diélectrique de l'objet.
