ABSTRACT:
In a magnetic resonance imaging apparatus comprising an array consisting of several rf coil elements, a bandpass filter is coupled to corresponding individual coils of the array, the outputs of the bandpass filters being connected to form a signal summing device. As a result, a substantial part of the imaging is sequentially performed, so that the construction of the image processing device may be simpler and the risk of image artefacts is reduced. The array forms a linear series of surface coils, a common axis of which coincides with the measurement gradient field direction.
