Abstract:
1. Apparatus for MR imaging of a subject comprising a MR magnet with gradient coil operable to generate a variable magnetic field to be applied to the subject; an RF transmit arrangement for generating an RF pulse in a transmit stage to be applied to the subject to be imaged such that the subject generates an MR signal in response to the magnetic field and the RF pulse applied; a receive coil arrangement for acquiring the MR signal in a receive stage; and a signal processing system for receiving the MR signal for carrying out signal processing by which an image is generated; the receive coil arrangement comprising: wherein said at least one receive coil is located at a spacing from said volume coil such that: the signal from said volume coil is induced onto said at least one receive coil at an efficiency of induction sufficient that the MR signal on said at least one receive coil is greater than the MR signal which would be generated in the absence of said volume coil; and mutual inductance between said volume coil and said at least one receive coil is insufficient to change the tuned common resonant frequency of the volume coil and the receive coil sufficiently to reduce the MR signal at said at least one receive coil to a value which is less than the MR signal which would be generated in the absence of said volume coil.
