Abstract
The invention relates to a method of MR imaging of an object (). The problem of the invention is to provide an improved MR imaging technique that enables fast and robust determination of spatial sensitivity profiles of RF receiving antennas () used in parallel imaging as well as Band/or Bmapping. The method of the invention comprises subjecting the object () to a stimulated echo sequence. Two or more stimulated echo signals (STE, STE*) are acquired, namely a direct stimulated echo signal (STE) and a conjugated stimulated echo signal (STE*), wherein at least one of the stimulated echo signals (STE, STE*) is received in parallel via an array of two or more RF receiving antennas () having different spatial sensitivity profiles, and wherein at least another one of the stimulated echo signals (STE, STE*) is received via a body RF coil () having an essentially homogeneous spatial sensitivity profile. Sensitivity maps indicating the spatial sensitivity profiles of the individual RF receiving antennas () of the array are derived by comparing the stimulated echo signals (STE, STE*) received via the array of RF receiving antennas () with the stimulated echo signals (STE, STE*) received via the body RF coil (). Moreover, the invention relates to a MR device () and to a computer program for a MR device ().
