Abstract
An MR tomograph, the magnet system (,) and gradient system of which permit access to the investigation volume along at least two essentially orthogonal axes, comprises a positioning system for the exact determination of the position of a manually guided manipulator (,) relative to the measuring object (,) which is investigated by means of imaging MR measurement and located in the investigation volume (,) of the MR tomograph (,); with a mounting frame (,) with which the manipulator (,) is connected via movable mechanics comprising a measuring means through which the respective spatial position of the manipulator (,) relative to the mounting frame (,) can be determined, wherein the measuring means of the movable mechanics does not utilize any MR signals and wherein the measured position of the manipulator (,) is displayed on the MR image. In this way, minimum-invasive operations, e.g. by means of a biopsy needle, can be carried out manually and the position of the manipulator, used in this connection, within the measuring object can be monitored by means of simultaneously recorded MR slice images during the operation and can be corrected, if necessary.
