Title (EN) ELECTROSTATICALLY DRIVEN IMAGING PROBE
(FR) SONDE D'IMAGERIE À ENTRAÎNEMENT ÉLECTROSTATIQUE
Abstract:
(EN) The present invention provides an imaging probe for imaging mammalian tissues and structures using high resolution imaging, including ultrasound and optical coherence tomography. The imaging probe uses electrostatic discharge for actuating a metalized cantilever which holds the end portion of imaging assembly which emits energy in the imaging probe device by holding the cantilever at a potential such that it is neither grounded or charged such that the only electrical path to ground is through a dissipative polymer forming part of the device which is enveloped by a wire or coil held at ground potential. A high voltage electrode attracts the metalized cantilever and the dissipative polymer is used to connect to the cantilever to ground causing the cantilever to move about thereby scanning the region in front of the probe.
(FR) L'invention concerne une sonde d'imagerie pour former une image de tissus de mammifère et des structures utilisant une imagerie haute résolution obtenue notamment par tomographie par cohérence ultrasonore et optique. La sonde d'imagerie utilise une décharge électrostatique pour actionner un porte-à-faux métallisé supportant la partie extrémité d'un ensemble d'imagerie qui envoie de l'énergie dans le dispositif de sonde d'imagerie par maintien du porte-à-faux à un potentiel tel qu'il n'est ni à la terre ni chargé, et que seul un chemin électrique à la terre traverse un polymère dissipatif formant une partie du dispositif qui est entouré d'un fil ou d'une bobine maintenue à un potentiel à la masse. Une electrode haute tension attire le porte-à-faux métallisé, et le polymère dissipatif est utilisé pour relier le porte-à-faux à la terre et entraîner son déplacement, ce qui permet de balayer la région opposée à la sonde.
