Title
(EN) THREE DIMENSIONAL ULTRASONIC GUIDANCE OF SURGICAL INSTRUMENTS
(FR) GUIDAGE ULTRASONORE EN TROIS DIMENSIONS POUR INSTRUMENTS CHIRURGICAUX
Abstract
(EN)
An ultrasonic imaging system is used to observe and guide insertion of a needle into the body to access a targeted surgical site. A two dimensional array probe scans a volumetric region including the surgical site and a multiplanar reformatter formats the resulting 3D echo dataset to form a sequence of spatially adjacent images in real time. A plurality of the spatially adjacent images are concurrently displayed in real time. As the clinician inserts the needle into the body its progress of insertion may be observed in one plane. But if the insertion path of the needle is not constrained to one plane but passes through numerous planes, the insertion path is seen in successive ones of the concurrently displayed adjacent images.

La présente invention concerne un système d'imagerie ultrasonore qui est utilisé pour observer et guider l'insertion d'une aiguille dans le corps et accéder à un site chirurgical cible. Une sonde de réseau en deux dimensions balaie une région volumétrique comprenant le site chirurgical et un reformateur multiplanaire formate l'ensemble de données d'écho en 3D obtenu pour former une séquence d'images spatialement adjacentes en temps réel. Une pluralité des images spatialement adjacentes sont affichées en même temps, en temps réel. Alors que l'aiguille est insérée dans le corps par le chirurgien, la progression de son insertion peut être observée sur un plan. Si la trajectoire d'insertion de l'aiguille n'est pas limitée à un plan et traverse de nombreux plans, la trajectoire d'insertion est observée sur des images successives parmi les images adjacentes affichées en même temps.
