METHOD AND APPARATUS FOR OPTIMIZING A MAGNETIC RESONANCE SEQUENCE

摘要

In a method for optimizing a magnetic resonance sequence of a magnetic resonance apparatus, a magnetic resonance sequence is provided to a computer, the sequence having a number of fixed point time intervals that are to be left unmodified, and a number of modifiable time intervals which may be optimized. The magnetic resonance sequence is automatically analyzed in the computer in order to identify the fixed point time intervals and the modifiable time intervals in the magnetic resonance sequence. At least one gradient pulse, which occurs during at least one modifiable time interval of the number of modifiable time intervals, is optimized by taking the first moment of this at least one gradient pulse into account.

1. A method for optimizing a magnetic resonance data acquisition sequence for operating a magnetic resonance apparatus, comprising:
providing a selected magnetic resonance sequence to a computer, said selected magnetic resonance sequence comprising a plurality of fixed point time intervals that are to be left unaltered and a plurality of modifiable time intervals that may be optimized; in said computer, automatically analyzing said selected magnetic resonance sequence to identify the fixed point time intervals therein and the modifiable time intervals therein; in said computer, automatically optimizing at least one gradient pulse that occurs during at least one modifiable time intervals among said plurality of modifiable time intervals, by automatically optimizing said at least one gradient pulse dependent on a first moment of said at least one gradient pulse, thereby producing an optimized magnetic resonance sequence; and making said optimized magnetic resonance sequence available as an electronic signal at an output of said computer.
