A computer-implemented method for operating an MR facility having a main magnet unit with a patient bore. A field of view (FOV) of the MR facility, defined by a main magnetic field's homogeneity, lies within the bore. A patient bench to position the patient within the patient bore is longitudinally movable. Additionally, a local coil arrangement with at least one coil element to measure MR data is freely positionable on the patient bench and/or a patient's body to be measured with respect to the longitudinal direction. The method includes: ascertaining position information of the local coil arrangement in the longitudinal direction using a measuring device when the patient bench is partially outside the patient bore; ascertaining recording information describing the local coil arrangement's position with respect to the FOV; and automatically positioning the patient bench in the longitudinal direction at an approach position ascertained from the position and recording information.

Magnetic resonance facility operation

A magnetic resonance apparatus has a scanner that has a patient receiving area, a position data acquisition unit, and a patient examination table of a patient positioning device. The table is movable within the patient receiving area. The position data acquisition unit detects a subarea, including an isocenter, of the patient receiving area, and provides position data to a speed regulating processor that regulates the speed of the table of patient positioning device depending on this position data.

Magnetic resonance apparatus and method for positioning an object on a patient positioning device within an isocenter of a magnetic resonance scanner

A method is provided for recording, with a magnetic resonance device, magnetic resonance data of a target region of a patient moved by their breathing. An optical camera arranged in a bore of the magnetic resonance device directed onto the patient is used. Image data of the patient recorded by the camera before and/or during the recording of the magnetic resonance data is evaluated to form breathing information describing the breathing state and the breathing information is used for triggering and/or movement correction and/or assessment of a process in which a patient holds their breath.
