Abstract
In a nuclear magnetic resonance apparatus and RF coil arrangement comprises two or more separable parts (51 and 53) adapted to be assembled around the body to be examined to form the coil arrangement. The parts are suitably arranged to be connected, when assembled, by adjustable coupling structure (55, 57, 59 and 61) so that the volume embraced by the coil arrangement may be adjusted. The invention enables the coil arrangement to be positioned more closely around a body being examined than is possible with conventional, unitary, tubular coil arrangements.
Claims3
An NMR apparatus including a coil arrangement for the application of and/or sensing of RF fields during examination of a body by means of the apparatus wherein said coil arrangement comprises at least two separate parts assemblable around a body to be examined to form said coil arrangement, said apparatus being suitable for use in examining the head of a patient, wherein said coil arrangement, when assembled, includes a former which supports the coils of the arrangement and which defines a window through which a patient whose head is within the coil arrangement may look out.
