Abstract
A known magnetic resonance device (1) operates with a coil array (c1 to cn) which serves as a detection coil whereby magnetic resonance signals are detected so as to form partial images of a sub-volume of an object (5) to be measured. A signal processing unit (9) forms an overall image from the partial images. Because the known device utilizes separate detection and signal acquisition channels, it is comparatively expensive and complex. In accordance with the invention, a simpler and less expensive magnetic resonance device (1) is obtained in that the device comprises a signal combination device (28) which shifts frequency ranges (s1 to sn) of individual coil elements in the coil array in respect of frequency and which forms, from the shifted frequency ranges (o1 to on) a sum signal (sm) in which the frequency ranges are separated from one another. As a result, many common circuits can be saved, without leading to a loss of flexibility of the device (1), so that the advantages of fully separated channels are retained.
