Method and Device for Thermal Breast Tumor Treatment with 3D Monitoring Function

An X-ray machine for monitoring thermal treatment of human tissue produces a reference exposure of the tissue to be treated prior to commencement of the treatment. Thermal treatment is performed subsequently. Check exposures are made with the X-ray machine during the treatment or also during treatment intervals. The check exposures are performed as partial volume exposures at a lower radiation load than the reference exposures. From a comparison of check exposures with the reference exposures, conclusions can be drawn concerning changes of tissue temperature and also tissue properties.
