Title (EN) SYSTEM AND METHOD FOR DRIVE MEMBER POSITION AND FLUID INJECTOR SYSTEM MECHANICAL CALIBRATION
(FR) SYSTÈME ET PROCÉDÉ D'ÉTALONNAGE MÉCANIQUE DE SYSTÈME D'INJECTEUR DE FLUIDE ET DE POSITION D'ÉLÉMENT D'ENTRAÎNEMENT
Abstract:
(EN) The present disclosure provides improved methods for calibrating the zero position of at least one drive member of an injector system is disclosed. Automated methods of position calibration of the drive member of a fluid injector are disclosed. These methods address sources of error in positional accuracy and fluid delivery inaccuracies, such as disposable syringe tolerance and injector wear over time. According to other embodiments of the present disclosure, methods and fluid injector systems for determining and correcting for the amount of slack in a fluid injection apparatus are described. An understanding of the calibration and the amount of slack in a fluid injection system allows a processor to correct for the slack, thereby ensuring more accurate fluid delivery to the patient and more accurate imaging processes.
(FR) La présente divulgation concerne des procédés améliorés d'étalonnage de la position zéro d'au moins un élément d'entraînement d'un système d'injecteur. La présente divulgation concerne également des procédés automatisés d'étalonnage de position de l'élément d'entraînement d'un injecteur de fluide. Lesdits procédés traitent les sources d'erreur dans la précision de position et les imprécisions de distribution de fluide, telles que la tolérance des seringues jetables et l'usure de l'injecteur dans le temps. Selon d'autres modes de réalisation, la présente divulgation concerne des procédés et des systèmes d'injection de fluide permettant de déterminer et de corriger la quantité de jeu dans un appareil d'injection de fluide. La compréhension de l'étalonnage et de la quantité de jeu dans un système d'injection de fluide permet à un processeur de corriger le jeu, garantissant ainsi une distribution de fluide plus précise au patient et des processus d'imagerie plus précis.
