Title (EN) THREE-DIMENSIONAL (3D) ULTRASOUND IMAGING SYSTEM FOR ASSESSING SCOLIOSIS
(FR) SYSTÈME D'IMAGERIE TRIDIMENSIONNELLE (3D) PAR ULTRASONS POUR ÉVALUER UNE SCOLIOSE
Abstract: front page image
(EN)A three-dimensional (3D) ultrasound imaging system (10) for assessing spinal structure problems comprises an ultrasound scanner (11) to capture ultrasound images, a spatial sensor (13) to record the position and orientation of the captured ultrasound images and a software module (21) to mark features of vertebra in the captured ultrasound images. The marked features (41) are connected by lines (42) in order to calculate angles and distances between the marked features (41) for the calculation of the Cobb angle and spinal rotation angle based on the calculated angles and distances, wherein the marked features (41) are reflections of the surfaces of the vertebra.
(FR)L'invention concerne un système (10) d'imagerie tridimensionnelle (3D) par ultrasons pour évaluer des problèmes de structure vertébrale, qui comprend un scanneur (11) à ultrasons permettant de saisir des images ultrasonores, un capteur spatial (13) qui enregistre la position et l'orientation des images ultrasonores saisies et un module logiciel (21), qui marque les caractéristiques de vertèbres dans les images ultrasonores saisies. Les caractéristiques marquées (41) sont reliées par des lignes (42) afin de calculer les angles et les distances entre lesdites caractéristiques (41), en vue de calculer l'angle de Cobb et l'angle de rotation vertébrale selon les angles et distances calculés ; les caractéristiques marquées (41) constituent des réflexions des surfaces de la vertèbre.
