Title
(EN) ACCOUSTIC WINDOW FOR IMAGING AND/OR TREATMENT OF BRAIN TISSUE
(FR) FENETRE ACOUSTIQUE POUR L'IMAGERIE ET/OU LE TRAITEMENT D'UN TISSU CEREBRAL
Abstract
(EN)
The invention relates to an acoustic window (1) designed to be implanted at an opening provided in the cranium (4) of a patient, said acoustic window (1) being intended to interact with an external ultrasonic probe (2) for emitting ultrasonic waves through said acoustic window (1), characterised in that the acoustic window comprises a plate (11) that has a plurality of through-openings (12), the distance (P) between these through-openings (12) being less than twice the wavelength of the ultrasonic waves emitted by the external ultrasonic probe (2).
(FR)
La présente invention concerne une fenêtre acoustique (1) apte à être implantée au niveau d'une ouverture ménagée dans la boîte crânienne (4) d'un patient, ladite fenêtre acoustique (1) étant destinée à coopérer avec une sonde ultrasonore externe (2) pour l'émission d'ondes ultrasonores à travers la fenêtre acoustique (1), remarquable en ce que la fenêtre acoustique comprend une plaque (11) incluant une pluralité d'ouvertures traversantes (12), la distance (P) des ouvertures traversantes (12) étant inférieures au double de la longueur d'onde des ondes ultrasonores émises par la sonde ultrasonore externe (2).
