Title (EN) STATIC CHARGE FILTER FOR CARDIAC ELECTRICAL SIGNALS CORRUPTED WITH STATIC CHARGE AND ROUTED TO AN ELECTROCARDIOGRAPH (EKG) MONITOR
(FR) FILTRE DE CHARGE STATIQUE POUR SIGNAUX ÉLECTRIQUES CARDIAQUES CORROMPUS PAR UNE CHARGE STATIQUE ET ACHEMINÉS VERS UN MONITEUR D’ÉLECTROCARDIOGRAMME (ECG)
Abstract:
(EN) A static charge filter (522) removes static charge in a cardiac electrical signal. The static charge filter includes a first amplifier (608) configured to amplify an input signal, which includes the cardiac electrical signal and static charge from an electrode, which is in a path of an X-ray beam. The static charge filter further includes a limiter (614) configured to limit a maximum voltage of the signal based on a predetermined clamping threshold, producing a voltage clamped signal. The static charge filter further includes a filter (616) configured to filter high frequency components of the voltage clamped signal, producing a filtered signal. The static charge filter further includes a second amplifier (620) configured to scale an amplitude of the filtered signal so that cardiac electrical signal in an output signal has a same voltage level as a voltage level of the cardiac electrical signal in the input signal.
(FR) La présente invention concerne un filtre de charge statique (522) qui élimine la charge statique dans un signal électrique cardiaque. Le filtre de charge statique comprend un premier amplificateur (608) configuré pour amplifier un signal d’entrée, qui comprend le signal électrique cardiaque est une charge statique provenant d’une électrode, qui est dans un trajet d’un faisceau de rayons X. Le filtre de charge statique comprend en outre un limiteur (614) configuré pour limiter une tension maximale du signal sur la base d’un seuil de contrainte de tension prédéterminé, produisant un signal de tension contraint. Le filtre de charge statique comprend en outre un filtre (616) configuré pour filtrer des composantes à haute fréquence du signal de tension contraint, de manière à produire un signal filtré. Le filtre de charge statique comprend en outre un deuxième amplificateur (620) configuré pour moduler une amplitude du signal filtré de sorte que le signal électrique cardiaque dans un signal de sortie ait un niveau de tension identique à un niveau de tension du signal électrique cardiaque dans le signal d’entrée.
