METHOD AND MAGNETIC RESONANCE APPARATUS FOR DETERMINING A PULSE SEQUENCE

摘要

In a method for determining a pulse sequence composed of multiple consecutive pulse sequence segments and multiple pre-pulses, the number of consecutive pulse sequence segments between two pre-pulses is determined on the basis of a randomizing algorithm. A pulse sequence determining device determines a pulse sequence for a magnetic resonance installation, device having an input interface for entering control protocol parameter values, a pulse sequence determining unit for determining the pulse sequence on the basis of the control protocol that has been entered, and a pre-pulse arrangement unit, which establishes the position of the pre-pulses between the pulse sequence segments in a randomly distributed manner.

1. A method for determining a pulse sequence for operating a magnetic resonance apparatus, said method comprising:
in a computer, accessing a randomizing algorithm; in said computer, configuring a pulse sequence for operating a magnetic resonance apparatus, said pulse sequence comprising a plurality of consecutive pulse sequence segments and a plurality of pre-pulses, by determining, with said randomizing algorithm, a number of said consecutive pulse sequence segments that occur between two pre-pulses of said pulse sequence; and making said pulse sequence with said number of consecutive pulse sequence segments between said two pre-pulses determined by said randomizing algorithm, available at an output of said computer in an electronic form that allows said pulse sequence to be used to operate said magnetic resonance apparatus.
