RF COIL

PURPOSE:To provide RF coils without the need for a connector and easily detachable by installing plural coils in a specific arrangement within a flexible main frame and making Q factor lower of each circuit in order to hold in check changes of mutual induction among the coils due to the deformation of the coils. CONSTITUTION:QD coils are two 8-shaped coils 2 and 3 arranged in a staggered manner at a specific spacing on a flexible coil sheet 1 and the coils 2 and 3 are connected to Q damp circuits 4 and 5, respectively. Further, each of the Q damp circuits, 4 and 5, is connected to a receiver via a composite processor 6. The coils 2 and 3 are positioned such that they are superimposed one over the other when the coil sheet 1 is wound around a body to be examined. The Q damp circuits 4 and 5 are intended to lower Q factor of the coils 2 and 3, respectively and the outputs from the Q damp circuits 4 and 5, respectively, are merged together in the composite processor 6.
