Claim Text:
1. A method for time synchronization of multiple components with each other in a magnetic resonance system, comprising: operating multiple components of a magnetic resonance data acquisition unit to generate a series of amplitude-modulated radio-frequency (RF) pulses and associated gradient fields, each of said amplitude modulated RF pulses comprising a signal envelope of that respective pulse that encompasses an RF portion at a frequency matched to a respective frequency of the nuclear spins, and thereby exciting said nuclear spins and deflecting magnetization of said nuclear spins in a slice of a subject in the data acquisition unit; detecting at least two spin signals that result from the deflection of the magnetization of said nuclear spins; in a processor, determining a phase difference between two of said spin signals; in said processor, determining, from said phase difference, at least one time shift between two variables that are generated by different components of said data acquisition unit among said multiple components, selected from the group consisting of said envelope of said amplitude-modulated RF pulses, said RF portion of said amplitude-modulated RF pulses, and one or more of said gradient fields; and from said processor, synchronizing said different components dependent on said at least one time shift.
