Abstract: Méthode de correction de non-uniformités en fonction des scènes (40), permettant de calculer et d'appliquer des facteurs de correction d'erreur de décalage à un signal vidéo correspondant à une image obtenue à partir d'un capteur d'image (11). Un signal vidéo obtenu à partir du capteur (11) est traité de façon qu'un vecteur représentant les facteurs de correction est formé, et ce vecteur est initialement mis à zéro. Chaque élément de ce vecteur représente un facteur de correction pour un détecteur particulier du capteur (11). Le vecteur est appliqué à chaque pixel de l'image par un processeur (13) à mesure que les pixels sont lus à partir du capteur (11). Pour mesurer l'erreur de décalage, l'image est séparée en régions orientées à la verticale, chacune comprenant un certain nombre de canaux. La moyenne de chaque canal pour une région est calculée (42), et un ensemble de vecteurs de région est formé, de sorte qu'à chaque région corresponde un vecteur de région. Chaque vecteur de région est ensuite filtré globalement à travers un filtre passe-haut, puis les contours dépassant un seuil prédéfini sont détectés (43) et marqués (44). Ensuite, chaque vecteur de région est séparé en sous-régions (45). Les sous-régions isolées sont filtrées localement à travers un filtre passe-haut. Une version établit la moyenne des facteurs de correction pour chaque vecteur de région verticale afin d'obtenir un unique vecteur de correction (48). Les facteurs de correction calculés pour chaque région verticale peuvent aussi être appliqués individuellement à chaque détecteur du capteur (11). Dans cette deuxième version, l'erreur de niveau de décalage dans chaque région pour chaque canal est calculée (49) et est indéfinie aux bords des contours. Les facteurs de correction correspondant à une région sont appliqués tandis que le détecteur (11) balaie la scène et observe une partie correspondant à cette région particulière. Les facteurs de correction sont lissés aux contours des régions afin d'éliminer le bruit due au contour dans les transitions.

Abstract: A magnetic resonance imaging apparatus includes a magnet system for producing a homogeneous magnetic field along the z axis. A plurality of wire conductors are arranged in a "bird cage" or "squirrel cage" configuration and are supplied with a circularly rotating RF field centered near the Larmor frequency .omega.o. The wire conductors also receive a voltage source V p having a frequency .omega.p, which is less than the Larmor frequency. The voltage source V p is rotated about the wire conductors at a frequency of .omega.~, which is much less than the frequency .omega.p, to successively apply the voltage V p to each pair of diametrically opposed wire conductors in a manner which is ordered as a spatial cylindrical harmonic rotating at a frequency w~. The voltage source V p produces electric fields in the object which, in turn, generate linear magnetic field gradients in the object. The voltage source V p phase encodes the signals detected from the object which thereby enables a transverse magnetization at each point within the object to be rapidly mapped back. With the invention, an image of the object is rapidly and continuously produced without requiring the use of the conventional gradient field coils and without any mechanical moving parts.
