In a nuclear magnetic resonance imaging system, a receive-only RF surface coil is fixedly supported on a non-metallic portable base by a non-metallic flexible support which permits the coil to be translated along any one of three orthogonal directions and to be rotated about any one of three orthogonal axes with respect to the base. The coil is therefore quickly movable to any position and orientation adjacent a patient being scanned in the magnetic resonance imaging system, and is immovably supported in the selected position and orientation during the scanning process. The coil may therefore be quickly and easily placed as close as possible to any region of interest of the patient's body without touching it, thereby optimizing the quality of the images obtained while avoiding undesirable image artifacts normally caused by movement of the coil with the patient's body motion. In one embodiment of the invention, a modular segmented joint assembly mounted on the base is connected to the surface coil through a ball jointed head. The surface coil is mounted in the head by hook and loop fasteners. The interior of the segmented joint assembly may be filled with a friction-increasing substance such as powder to increase stiffness of the assembly. Another segmented joint assembly supports a multi-mirror assembly on the base, allowing the patient to see non-inverted images outside of the MRI enclosure.

Variable position surface coil stabilizer for magnetic resonance imaging

A device for producing plural lines on a film bearing a radiographic image of a portion of the body of a living being to facilitate the location of a part of the being's body within that image. The device comprises a flexible substrate formed of a porous, translucent or transparent material having lines of a radio-opaque material disposed thereon and is made by the application a slurry of a plastisol material and lead particles in the line pattern on the substrate and then drying the slurry. The device is used by applying it over a selected portion of the body of a being, disposing a radiosensitive film under the selected portion of the being's body, exposing the film to radiation, and thereafter developing the film. The resulting radiographic image of the selected portion of the being's body thus has indicator lines crossing it which facilitates the demarcation of a desired portion of that image. A marking instrument, e.g., a marking pen, can be applied to the substrate at predetermined locations thereon while the device is on the being to mark the body of the being at the selected location.

A device for producing plural lines on a film bearing a radiographic image of a portion of the body of a living being to facilitate the location of a part of the being's body within that image. The device comprises a flexible substrate having lines of a radio-opaque material disposed thereon and is made by the application a slurry of a plastisol material and lead particles in the line pattern on the substrate and then drying the slurry. The device is used by applying it over a selected portion of the body of a being, disposing a radiosensitive film under the selected portion of the being's body, exposing the film to radiation, and thereafter developing the film. The resulting radiographic image of the selected portion of the being's body thus has indicator lines crossing it which facilitate the demarcation of a desired portion of that image. In one preferred embodiment the substrate of the device includes plural openings in the lines so that a marking instrument, e.g., a marking pen, can be inserted through at least one selected opening while the device is on the being to mark the body of the being at the selected location.

An eye patch is provided for preventing opening of an eye and preventing corneal abrasion. The patch comprises a compressible planar pad having a configuration which fits within the eye socket to permit easy contact with the outer surface of the eyelids over a closed eye. The planar pad is flexible to facilitate conforming to the outer surface of the lids of the eye. One surface of the pad has an adhesive with a low to moderate adhesion applied thereto to permit securement of the lids in a closed position while permitting removal of the patch with minimal patient discomfort.
