Claim:
1. A method configured for generating magnetic resonance (MR) images with slice multiplexing, comprising: with a control computer, operating an MR data acquisition unit in order to generate a basic magnetic field having a basic field direction, and in order to radiate a first radio-frequency pulse that deflects a first nuclear spin system in a first slice of a subject, thereby giving said first spin system in said first slice a magnetization in a plane that is transverse to said basic field direction in which said magnetization has a phase that exhibits a phase evolution represented as a first coherence curve; with said control computer, operating said MR data acquisition unit in order to radiate a second radio-frequency pulse that deflects a second spin system in a second slice of the subject, thereby giving said second spin system in said second slice a magnetization in another plane that is transverse to said basic field direction in which said magnetization has a phase that exhibits a phase evolution represented as a second coherence curve; with said control computer, controlling operation of said MR data acquisition unit in order to cause a beginning of a second radio-frequency pulse to be time-shifted by a difference time period, with respect to a beginning of said first radio-frequency pulse, that is shorter than a duration of said first radio-frequency pulse; with said control computer, operating said MR data acquisition unit in order to impress a correction phase on at least one of said first and second spin systems and in order to thereafter detect, in a given signal detection time period, a first signal representing said magnetization of said first nuclear spin system resulting from said deflection of said first nuclear spin system and in order to detect a second MR signal representing said magnetization of said second spin system resulting from said deflection of said second nuclear spin system; with said control computer, operating said MR data acquisition unit in order to impress said correction phase, whereby each of said first and second coherence curves is rephased thereby causing detection of said first and second MR signals simultaneously in said given signal detection time period; and from said control computer, making the detected first and second MR signals available in electronic form as a data file.
