Autor: J. Fred Eastham, David Jonathan Herlihy, I. R. Young, R.J. Hill-Cottingham, Joseph V. Hajnal, Glyn A. Coutts, Michael Burl

Publikováno v: Magnetic Resonance in Medicine. 41:636-638

An RF coil, made by twisting a conventional wire loop, was tuned to form an extended sensor to provide an effective method of showing the track of a catheter. A twisted-pair coil can be made small enough in diameter to pass through needles in common

Tuned fiducial markers to identify body locations with minimal perturbation of tissue magnetization

Autor: Michael Burl, Glyn A. Coutts, I. R. Young

Publikováno v: Magnetic Resonance in Medicine. 36:491-493

A fiducial marker is described in which a small cell containing a short T1 solution is surrounded by single- or quadrature-tuned windings. It is shown how these can be used to enhance small externally applied RF pulses, which do not significantly per

Examples of the design of screened and shielded RF receiver coils

Autor: Michael Burl, I. R. Young

Publikováno v: Magnetic resonance in medicine. 36(2)

Three methods of screening RF surface coil receivers are discussed. The aim is to design coils with very much greater sensitivity on one side than on the other so that signal and noise contributions from unwanted regions of the body can be minimized.

MR-guided biopsy of the breast after lumpectomy and radiation therapy using two methods of immobilization in the lateral decubitus position

Autor: A. S. Hall, Michael Burl, Claire Vernon, Nandita M. deSouza, Jane E. Schwieso, Rakesh Puni, Glyn A. Coutts, Thomas Krausz, Donald W. Kormos

Publikováno v: Journal of magnetic resonance imaging : JMRI. 5(5)

We describe two methods of breast immobilization using the lateral decubitus position to increase patient comfort and access to the axillary tail for MR-guided biopsy in the postsurgical or irradiated breast. The first method uses a compression devic
