<p>The invention relates to a magnetic resonance method, wherein high-frequency pulses and magnetic gradients (gx, gy, gz) are produced in order to selectively excite an object to be examined. According to the invention, the magnetic resonance method is characterized in that a magnetic resonance signal s(t) is produced according to the following signal equation: (I), wherein (II) denotes a desired transverse magnetization after the selective excitation, t denotes a time, (III) denotes a position vector, and T denotes a duration of a pulse, wherein s(t) denotes a magnetic resonance signal, V denotes an examination volume, T 2 denotes a transverse relaxation time, and ? s denotes a shift of the resonance frequency. The invention further relates to a magnetic resonance tomograph for carrying out the magnetic resonance method.</p> |
