Degenerative aortic stenosis is highly prevalent in the aging populations of industrialized countries and is associated with poor prognosis. Surgical valve replacement has been the only established treatment with documented improvement of long-term outcome. However, many of the older patients with aortic stenosis (AS) are high-risk or ineligible for(More)
A system for thermoradiotherapy of cervical carcinoma is presented, that allows combination of high-dosed afterloading short-time therapy by means of the technique being available in the GDR (DEKATRON) with the equipment CALOTHERM, constructed in Institut M. v. Ardenne. The first clinical experiences (3 patients) show, that the expected target temperature(More)
An applicator system for the radiothermotherapy of gynecological tumors has been developed. The concept is based on combining high-dose rate afterloading therapy with local hyperthermia (27.12 MHz). The main applicator, the rf-gamma applicator consists of a guide tube for the gamma source, an electrode system and a cooling system. Isodoses and isotherms can(More)
Medical imaging procedures are providing qualitative and, increasingly, quantitative diagnostic information on the morphology and function of the human organism. As possibilities for communication and data processing continue to grow, they are also being applied in the field of therapy. Taking combined local radiotherapy and thermotherapy for the treatment(More)
This paper describes a new type of applicator system for the intracavitary radiothermotherapy of gynaecological tumours. Hyperthermia and radiation can be delivered by one and the same applicator. The hyperthermia is delivered by a modified capacitive heating technique (27.12 MHz) combined with cooling systems, the radiation by the numerically controlled(More)
