Magnetic resonance facility and a method for operating a magnetic resonance facility having a patient table

Abstract

A method for operating a magnetic resonance facility is provided herein. The facility has a main magnet unit with a patient-receiving area, a movable, controllable patient table for positioning a patient in the patient-receiving area, a table control unit for controlling the patient table, and, on the main magnet unit, an operating facility that communicates with the table control unit, for operation of the patient table by a user. The operating facility has a first, electronic operating device for setting control parameters for a movement of the patient table to be performed, and a second, mechanical operating device for triggering the movement. In a safe operating mode, control parameters that have been set are communicated from the first operating device to the table control unit over a first communication channel, and a trigger signal, suitable for triggering the movement defined by the control parameters, is communicated from the second operating device, over two redundant second communication channels that are at least logically separated, to the table control unit, and processed separately there, wherein the movement is only triggered when there is a match between the trigger signal received over the two communication channels.
