A shim coil device for compensating for basic magnetic field inhomogeneities during medical magnetic resonance imaging of a breast of a patient, said shim coil has a housing with a contact surface that configures to bear against a patient, and at least one shim coil element having a shim coil axis. The shim coil is arranged on the patient such that the at least one shim coil axis has an angle of inclination &#x3b1; to the contact surface and/or to a patient surface, where &#x3b1; is &#x2265;45&#xb0; and &#x3b1; is &#x2264;135&#xb0;.

Shim coil device and a magnetic resonance coil system having a shim coil device

In a method and device to detect interference signals in magnetic resonance spectroscopy signals a comparison signal is computationally reconstructed that optimally approximates a measured, detected magnetic resonance spectroscopy signal. The comparison signal forms spectral components of resonance lines of the measured magnetic resonance spectroscopy signal. A residual is calculated from the difference of the two signals (comparison signal and magnetic resonance spectroscopy signal) in the frequency representation. The interference signals are determined from the residual.

Magnetic resonance method and system to detect interference signals in magnetic resonance spectroscopy signals

In a method for evaluating data of a magnetic resonance signal, a baseline is modeled and at least one metabolite signal is modeled. The modeling of the baseline ensues based on magnetic resonance data in the time domain, and using only data that begins with the magnetic resonance signal and having a length that is shorter than the duration of the overall magnetic resonance signal.

Method for evaluating magnetic resonance spectroscopy data using a baseline model

In a method for evaluating data that are generated by a magnetic resonance technique and contain spectroscopic information, at least two spikes of a spectrum of the data are detected, position that the detected spikes exhibit relative to one another within the spectrum is compared to spikes of known substances; and a known substance is allocated to the detected spikes given a coincidence of the comparison.
