Definitions

  • the field of the invention is magnetic resonance imaging (MRI) and in particular local coils for use in receiving MRI signals for the region of the shoulder.
  • MRI magnetic resonance imaging
  • RF radio frequency
  • the nuclear spins are excited into precession at their Larmor frequencies.
  • the RF excitation signal is applied to the imaged object at the same time as a magnetic field gradient. The gradient field causes only the nuclei in a slice through the object to have the necessary resonant frequency to be excited into resonance.
  • Local coils may be particularly useful for imaging the soft tissue of the shoulder.
  • supporting the coils structure in the area of the shoulder can be difficult because of the complex surface presented by this region of the body.
  • One solution, presented by U. S. Patent 5,136,244 assigned to the same assignee as the present application and hereby incorporated by reference provides a shoulder local coil using opposed "paddles" each holding a coil that can be fit to the front and back of a patient's shoulder through a mechanically adjustable joint. The rigid construction ensures minimal movement of this coil during the imaging process.
  • a local coils for the shoulder may be constructed using flexible, fabric-like, materials that may be wrapped around the shoulder to fit a variety of individuals.
  • the coils may be multiple phased array coil loops.
  • the present invention provides local coil 8 suitable for use in imaging the shoulder.
  • the local coil 8 may include a base 10 that may fit against an upper surface of a patient support table 11 on an MRI device (not shown) to be supported under a patient lying on the patient support table 11.
  • the base 10 may have a lower surface 12 conforming generally to the upper surface of the patient support table 11 and an upper planar surface 14 against which the patient presses.

Abstract

L'invention porte sur une bobine locale d'imagerie de l'épaule par IRM présentant une enveloppe cupuliforme comportant des éléments rigides qui entourent l'épaule en se courbant autour de l'épaule le long de deux axes. Lesdits éléments rigides peuvent pivoter l'un par rapport à l'autre pour faciliter la mise en place de l'enveloppe autour de l'épaule et s'adapter à la taille des différents patients.
