摘要： In accordance with a method for operating an MRT system a first MR recording is performed so as to map an object to generate first MR data that represents the object. The first MR recording is performed in accordance with a first k-space scanning scheme and during the first MR recording at least one first excitation pulse is transmitted. A second MR recording that is different from the first MR recording is performed to generate second MR data and a noise component is determined in dependence upon the second MR data by a computing unit and the noise component represents an influence of at least one external noise source. An MR image is generated by the computing unit in dependence upon the first MR data and in dependence upon the noise component.

摘要： The disclosure relates to a magnetic resonance tomography system and to a method for operation of the magnetic resonance tomography system. The magnetic resonance tomography system has a magnetic unit, which is configured to change a homogeneous magnetic field B0 with a magnetic field strength, which may vary between a first predetermined value on exciting nuclear spins and a second predetermined value on receiving magnetic resonance signals, in a measuring volume in a short, predetermined time, controlled by the magnetic resonance tomography system.

摘要： The disclosure relates to a method for determining an item of evaluation information from a reception signal received by a magnetic resonance apparatus, a computer program product for carrying out such a method and a magnetic resonance apparatus. The method provides that a useful signal having a first frequency band is generated. The magnetic resonance apparatus is configured to generate a magnetic resonance signal in a second frequency band. The first frequency band lies at least partially, (e.g., completely), within the second frequency band. A reception signal is received by a receiving unit of the magnetic resonance apparatus. From the reception signal, an item of evaluation information is determined which characterizes the useful signal.

摘要： In a method and magnetic resonance apparatus for monitoring functioning of a cooling system of the apparatus, at least some apparatus components, that are to be cooled by the cooling system, have respective temperature sensors in thermal communication therewith. A start temperature of at least one of the components is determined by at least one of the sensors, and a computer determines, from the start temperature, at least one comparison variable that describes a reference temperature change due to power input to the respective component. The at least one temperature sensor provides the computer with a measured variable that describes actually occurring temperature change due to the power input. The computer compares the measured variable with the comparison variable and determines whether the comparison result fulfills an action criterion and, if so, the computer initiates implementation of an action associated with the action criterion.
