Patent ID: 7218113

Claim:
A method for operating a magnetic resonance system, comprising the steps of: prior to acquiring diagnostic magnetic resonance data from an examination volume of a subject with a data acquisition pulse sequence including a plurality of RF pulses emitted from an RF antenna, individually radiating said plurality of RF pulses into the examination volume and determining an effective volume within said examination volume for each of said RF pulses, and, for each of said RF pulses, measuring a B 1 field distribution produced in the effective volume for that RF pulse; and acquiring said diagnostic magnetic resonance data by applying said data acquisition pulse sequence to said subject and, in said data acquisition pulse sequence, optimizing each of said RF pulses by electronic shimming to homogenize the B 1 field distribution produced thereby in the effective volume of each shimmed RF pulse; and reconstructing an image of the subject from the acquired magnetic resonance diagnostic data.
