Title (EN) ULTRASOUND STRAIN IMAGING IN TISSUE THERAPIES
(FR) THERAPIES D'IMAGERIE DE TISSUS PAR ULTRASONS SOUS CONTRAINTE
Abstract: front page image
(EN)Disclosed is a system and method for providing ultrasound strain imaging of a soft tissue, such as a prostate, so that the soft tissue may be more precisely targeted during radiation treatment. The system includes a mechanical arm with a pressure interface for applying incremental pressure to the patient's abdomen, and a data system for correlating the ultrasound signals acquired before and after each application of incremental pressure. By correlating the pre and post-pressure ultrasound signals, acoustic interfaces corresponding to the prostate, which define the contours of the prostate, may be identified and displayed. Further, data corresponding to the contours of the prostate may be provided to a linear accelerator to enable the linear accelerator to more precisely target the prostate.
(FR)L'invention porte sur un système et un procédé d'imagerie par ultrasons sous contrainte de tissus mous tel que la prostate permettant de cibler avec une plus grande précision un tissu mou lors d'une radiothérapie. Le système comporte un bras mécanique muni d'une interface de pression appliquant par degrés une pression sur l'abdomen du patient, et un système de traitement de données corrélant les signaux des ultrasons captés avant et après chaque application de la pression. Cette corrélation entre les signaux permet d'identifier et d'afficher les interfaces acoustiques correspondant à la prostate et en définissant les contours. En outre, les données correspondant aux contours de la prostate peuvent être transmises à un accélérateur linéaire qui peut ainsi cibler la prostate avec une plus grande précision.
