Abstract
In a combined radiofrequency antenna and gradient coil in a magnetic resonance imaging apparatus, radiofrequency signals are coupled into conductor loops of the gradient coil so that these loops are operated as elements of a radiofrequency antenna. The installation space for a separate radiofrequency antenna can thus be saved. Given the same patient-receiving volume, the diameter of the cylindrical opening of a magnet or the spacing between pole shoes can be reduced, so that the magnets can be more economically built.
