摘要：
The invention relates to a method of MR imaging of at least a portion of a body (10) of a patient placed in an examination volume of an MR device (1). The object of the invention is to provide an improved i.e. faster parallel imaging technique. The invention proposes to acquire a survey signal data set (21 22) at a low image resolution which survey signal data set (21 22) includes MR signals received in parallel or successively via a volume RF coil (9) and via a set of array RF coils (11 12 13). Spatial sensitivity profiles (23) of the array RF coils (11 12 13) are determined from the low resolution data. As a next step a reference scan is performed in which a reference signal data set (25) is acquired at intermediate resolution solely via the array RF coils (11 12 13).
