Abstract: In a manipulator for use in a closed magnetic resonance tomograph with an MRT channel extending therethrough for receiving a patient's rest supporting a female patient laying on her stomach during mammography, a support arm having a front end with a receiving housing for accommodating various instruments for the treatment of the patient is provided, which support arm is movable into the channel together with the patients rest and which is positionable relative to the patients mamma steplessly in every direction and operable in a position adjacent to the mamma for any desired treatment of the mamma.

Abstract: The invention relates to a device for detecting, using differential diagnosis, and for treating tumors. The inventive device enables, in practically one operation, a tumor-selective and tissue-protective representation, a reduction in the duration of treatment and/or an extension of the treatment to larger tissue areas. The device includes a combination of the following elements: at least one electrode pair (12, 13) having electrodes fitted substantially diametrically to the organism/organism part (10) in a cross-sectional plane; the electrode pair detecting resistance signals in different orientations in relation to the organism/organism part (10); a measuring device (17) for converting the resistance signals into resistance values; and an evaluation device (20) which receives the resistance values for evaluation and representation.
