Abstract
A magnetic resonance tomography unit includes a magnet unit having a magnetic controller for generating a homogenous magnetic field. The magnetic controller is configured to change the homogenous magnetic field in a short, predetermined time within image acquisition of an object under examination, such that a Larmor frequency for a predetermined layer of the object under examination remains in a predetermined frequency range. A layer in the object under examination is selected and a value for the homogenous magnetic field, in which the Larmor frequencies of the nuclear spins of the layer lie in a predetermined frequency band, is determined by a control unit taking into account a predetermined magnetic field gradient. The established value for the homogenous magnetic field and the predetermined magnetic field gradient is set by the magnetic controller, and an excitation pulse, frequencies of which only lie in the predetermined frequency band, is emitted.
