Abstract
A magnetic resonance (MR) tomography apparatus has an array composed of a number n of single coils Eto acquire reception signals I. The tomography apparatus is operated by a method that includes the following steps. For each single coil E, a processor determines, or is provided with, an individual reception sensitivity profile in positional space r B1(r). An examination subject introduced into the MR tomography apparatus is scanned to acquire reception signals I(k) in the frequency domain with the n reception coils E. Fourier-transformed signals IF(r) are determined from the reception signals I(k). Complexly corrected signals ĨF(r) are determined on the basis of the signals IF(r) and the individual reception sensitivity profiles B1(r). A sum signal MR(r) is determined by complex addition of the corrected signals ĨF(r). Image data of the examination subject are reconstructed on the basis of the sum signal MR(r).
