Contribution to nuclear magnetic resonance imager using permanent magnets

Creators

Description

After some recalls of nuclear magnetic resonance, ways to get a stable and homogeneous magnetic field are studied with permanent magnets. Development of correction coils on integrated circuits has been particularly stressed. Gradient coil specific systems have been studied taking in account ferromagnetic material presence. Antenna system has been improved and possibility of image obtention with the prototype realized has been shown

Abstract (French)

Apres avoir rappele les principes de l'imagerie par resonance magnetique nucleaire, on etudie les moyens qui permettent d'obtenir un champ magnetique stable et homogene avec des aimants permanents. Un effort particulier a ete apporte a la mise au point de bobines de correction sur circuits imprimes. On etudie ensuite des systemes specifiques de bobines de gradient en tenant compte de la presence de materiaux ferromagnetiques. Enfin, apres avoir apporte une amelioration au systeme d'antenne on montre qu'il est possible d'obtenir des images avec le prototype realise
