Title
(EN) MAGNETIC RESONANCE THERMOGRAPHY: HIGH RESOLUTION IMAGING FOR THERMAL ABNORMALITIES
(FR) THERMOGRAPHIE À RÉSONANCE MAGNÉTIQUE : IMAGERIE HAUTE RÉSOLUTION POUR LES ANOMALIES THERMIQUES
Abstract
(EN) A magnetic resonance scanner (12) is configured for themographic imagin. One or more processors (28)receive (56)thermal image data from the magnetic resonance scanner and reconstruct at least one thermal image in which each voxel includes a measure of temperature change. The one or more processors identify (58)thermally abnormal voxels. A display (44)displays at least one reconstructed image with the identified abnormal thermal locations.
(FR) L'invention concerne un scanner à résonance magnétique (12) configuré pour l'imagerie thermographique. Un ou plusieurs processeurs (28) reçoivent (56) des données d'images thermiques du scanner à résonance magnétique et reconstruisent au moins une image thermique, dans laquelle chaque voxel comprend une mesure de changement de température. Le ou les processeurs identifient (58) les voxels thermiquement anormaux. Un écran (44) affiche au moins une image reconstruite avec les emplacements thermiques anormaux identifiés.
