(EN) METHOD AND SYSTEM FOR PREDICTIVE PHYSIOLOGICAL GATING
(FR) PROCEDE ET SYSTEME D'ACTIVATION PHYSIOLOGIQUE PREDICTIVE
Abrégé
(EN)
A method and system (100) for physiological gating is disclosed. A method and system (100) for detecting and predictably estimating regular cycles of physiological activity or movements is disclosed. Another disclosed aspect of the invention is directed to predictive actuation of gating system components. Yet another disclosed aspect of the invention is directed to physiological gating of radiation treatment based upon the phase of the physiological activity. Gating can be performed, either prospectively or retrospectively, to any type of procedure, including radiation therapy or imaging, or other types of medical devices and procedures such as PET, MRI, SPECT, and CT scans.

L'invention concerne un procédé et un système (100) d'activation physiologique. L'invention concerne également un procédé et un système (100) de détection et d'estimation prévisible de cycle d'activité ou de mouvements physiologiques. Un autre aspect décrit de l'invention concerne l'actionnement prédictif de composantes de système d'activation. Un autre aspect décrit de l'invention concerne l'activation physiologique d'un traitement par rayonnement basée sur la phase de l'activité physiologique. L'activation peut être exécutée, soit prospectivement soit rétrospectivement, dans n'importe quel type de procédure, notamment en radiothérapie ou en imagerie, ou dans d'autres types de dispositifs et de procédures médicaux tels que TEP, IRM, en tomographie monophotonique d'émission (SPECT) et en tomodensitométrie.
