Abstract: A magnetic resonance tomography device has a magnet system that generates a gradient field; with a local coil that receives a magnetic resonance signal; and with a localization system that is fashioned to locate the local coil. The localization system has a number of magnetic field sensors that are integrated with the local coil and fashioned to detect the gradient field. Such a device is used in a corresponding method for localization of a local coil in a magnetic resonance tomography device, and a local coil is fashioned so as to be suitable for this purpose.

Abstract: In a method and device for field quality testing of a magnetic resonance antenna arrangement of a magnetic resonance system composed of multiple antenna elements, a test signal is fed into the respective antenna elements by a transmission antenna and the test signal, or a noise signal that occurs with no signal fed to the respective antenna elements, is determined at a receiver unit for each of at least some of the individual antenna elements. The noise received noise signals and/or test signals are analyzed with regard to specific characteristic data and a quality state of the magnetic resonance antenna arrangement is determined based thereon.

Abstract: A device for recovering a temporal reference in a free-running magnetic resonance tomography (MRT) receive chain includes a time reference encoder and a time reference decoder. The time reference encoder is configured to generate a modulation signal as a function of a reference clock, where the modulation signal is configured for a correlation with a temporal resolution less than a maximum predetermined phase deviation and a maximum that may clearly be identified. The time reference decoder is configured to receive, via the first signal input, a receive signal as a function of the modulation signal, perform a correlation with a reference signal, and generate a signal as a function of a temporal reference of the modulation signal in the receive signal in relation to the reference signal.
