Patent ID: 10429474

Abstract:
A magnetic resonance (MR) tomography apparatus has an array composed of a number n of single coils Ei to acquire reception signals Ii. The tomography apparatus is operated by a method that includes the following steps. For each single coil Ei, a processor determines, or is provided with, an individual reception sensitivity profile in positional space r B1i−(r). An examination subject introduced into the MR tomography apparatus is scanned to acquire reception signals Ii(k) in the frequency domain with the n reception coils Ei. Fourier-transformed signals IFi(r) are determined from the reception signals Ii(k). Complexly corrected signals ĨFi(r) are determined on the basis of the signals IFi(r) and the individual reception sensitivity profiles B1i−(r). A sum signal MR(r) is determined by complex addition of the corrected signals ĨFi(r). Image data of the examination subject are reconstructed on the basis of the sum signal MR(r).
