Abstract
A computer program product (1344, 1346, 1348) comprising machine executable instructions for performing a method of acquiring a magnetic resonance image (1342), the method comprising the steps of: acquiring (100, 200, 300) a set of coil array data (1334) of an imaging volume (1304) using a coil array (1314), wherein the set of coil array data comprises coil element data acquired for each antenna element (1316) of the coil array; acquiring (102, 202, 302) body coil data (1336) of the imaging volume with a body coil (1318), wherein the body coil data and/or the array coil data is sub-sampled; reconstructing (104, 204, 206, 304, 306, 308) a set of coil sensitivity maps (1338) using the set of coil array data and the body coil data, wherein there is a coil sensitivity map for each antenna element of the coil array; acquiring (106, 208, 310) magnetic resonance imaging data (1340) of the imaging volume using a parallel imaging method (1332); and reconstructing (108, 210, 312) the magnetic resonance image using the magnetic resonance imaging data and the set of coil sensitivity maps.
