Abstract
(EN) A motion compensation system for tracking and compensating for patient motion during a medical imaging scan comprises an optical marker comprising an optically visible pattern and a mounting portion; a first optical detector positioned to digitally image the optically visible pattern along a first line of sight; a second optical detector positioned to digitally image the optically visible pattern along a second line of sight; a tracking engine configured to determine a pose of the object in six degrees of freedom by analyzing images from the first and second optical detectors; and a controller interface configured to generate tracking information based on the pose and to electronically transmit the tracking information to a scanner controller to enable compensation within a medical imaging scanner for object motion.
(FR) L'invention concerne un système de compensation de mouvement, destiné à suivre et compenser des mouvements du patient pendant un balayage d'imagerie médicale, qui comprend un marqueur optique contenant un motif visible optiquement et une partie de montage ; un premier détecteur optique placé pour donner une image numérique du motif visible optiquement le long d'une première ligne visuelle ; un second détecteur optique placé pour donner une image numérique du motif visible optiquement le long d'une seconde ligne visuelle ; un moteur de suivi configuré pour déterminer une pose de l'objet à six degrés de liberté par l'analyse des images provenant des premier et second détecteurs optiques ; et une interface de commande configurée pour créer des informations de suivi sur la base de la pose et pour transmettre électroniquement les informations de suivi à un contrôleur de scanner, afin de permettre de compenser un mouvement de l'objet à l'intérieur d'un scanner d'imagerie médicale.
