Abstract
The invention relates to an MR method and an MR device for the formation of MR images of an examination zone of an object (10) to be examined. An excitation coil (21) which includes at least one movable and/or flexible excitation coil (19) is used therein for the excitation of the examination zone to be imaged and/or a receiving coil system which includes at least one movable and/or flexible receiving coil (61, 62, 63) is used for the acquisition of MR data from the examination zone. In order to enable the acquisition of MR images with a high accuracy and notably a high spatial and temporal resolution, it is proposed to acquire information concerning the position and orientation of the receiving coils (61, 62, 63) or the at least one excitation coil (19) and to utilize the acquired information for the correction of the input data for the reconstruction or for the correction of the excitation signal of the at least one excitation coil (19). Motions and/or deformations of coils during the acquisition of MR data can thus be taken into account.
