ABSTRACT:
The apparatus including a mainly cylindrical RF coil (9) having a central axis (33) which extends in its longitudinal direction, which coil has a number of axial conductor elements (35) which extend parallel to the central axis across a mainly cylindrical surface, and end conductor elements (37) which extend around the central axis near the ends of the axial conductor elements. The axial conductor elements (35) extend pair-wise diametrically relative to the central axis and the RF coil (9) is arranged to generate a substantially cosinusoidal current distribution as a function of the position of the axial conductor elements on the circumference of the cylinder in order to enable generation and/or reception of a substantially uniform RF magnetic field which is oriented perpendicularly to the cylinder axis. Each of the end conductor elements (37) consists of a number of loop conductor segments (39) which corresponds to the number of pairs of axial conductor elements (35). Each loop conductor element extends through an are of 180.degree. about the central axis (33) and electrically interconnects corresponding ends of a pair of axial conductor elements which are diametrically situated relative to the central axis. In conjunction with the loop conductor segments (39) connected to their ends, each pair of axial conductor elements (35) constitutes a coil element (41) which is composed of a number of turns of an elongate electrical conductor. The designer has great freedom as regards the choice of the self-inductance of the coil elements (41), and hence as regards the choice of the resonance frequency of the RF coil (9).
