Definitions

  • NMRSAMPLEHOLDER relates to an NMR (Nuclear Magnetic Resonance) probe and associated components which enable Magnetic Resonance Spectroscopy (MRS) and Magnetic Resonance Imaging (MRI) to be performed on subjects such as living tissues and organs, as well as inanimate materials.
  • the invention is directed to a removable sample holder for use with the probe, means for precise positioning of the sample holder relative to the probe, and means for secure and accurate fixing of the sample relative to the holder.
  • the fixing means comprises a transverse bar 20 which is located behind the upper incisor teeth of the mouse, thereby fixing the cranium in the axial direction.
  • the bar 20 is mounted on a sliding element 21 which is threadedly connected to a threaded rod 22 which functions as a lead screw.
  • the threaded rod 22 is connected to a manually operable knob 23 on the exterior of the shroud 12.

Abstract

Porte-échantillon (10) destiné à être utilisé avec une sonde de résonance mangétique nucléaire (RMN), comprenant un élément profilé (11) dans lequel on peut placer un petit animal ou un échantillon. L'échantillon est fixé longitudinalement et de manière à pouvoir tourner par rapport à l'élément profilé (11), par des dispositifs de fixation comprenant une barre transversale (20) et des mâchoires (24, 25), ces deux types d'éléments étant réglables depuis l'extérieur du porte-échantillon. Des gaz anesthésiques sont distribués par le tuyau (17) et les vapeurs résiduelles sont extraites par aspiration. La position axiale du porte-échantillon par rapport au résonateur de sonde associé est réglable au moyen d'un bouton (44) situé à l'extérieur du résonateur.
