Ian Robert Young, Michael Burl: Marker for magnetic resonance imaging. Picker International, Timothy B Gurin, John J Fry, April 7, 1998: US05735795 (31 worldwide citation)

A marker and probe for use in magnetic resonance imaging includes a vial for insertion within the body. The vial contains a material having a spin-lattice relaxation time less than that of the material of the body in a region being imaged. A coil arrangement having at least one coil tuned to the fre ...

An imaging system produces an image of an internal part of an object and a representation of a tool, which representation corresponds to the position of the tool with respect to the actual object. An imaging apparatus defines an examination region. After an image of the object is obtained, the objec ...

A flexible catheter or other object for insertion into an object is designed for use in connection with magnetic resonance (MR) imaging techniques. The catheter carries a closed loop coil arrangement tuned to the RF excitation frequency used in operation of an MR imager. The coil arrangement include ...

Microstructured materials which can be tuned to a particular range of r.f. frequencies to display particular magnetic permeabilities have been proposed. A typical material is made of an array of capacitive elements e.g. spirals or rolls of conducting material on a non-conducting substrate. These mat ...

A material having magnetic permeability at r.f. frequency, for example a microstructured magnetic material has a magnetic permeability of negative value but unity magnitude over a particular r.f. frequency range. The singularity in the flux pattern has the result that magnetic resonant disturbances ...
