Title (EN) EXACT LOCAL COMPUTED TOMOGRAPHY BASED ON COMPRESSIVE SAMPLING
(FR) TOMOGRAPHIE LOCALE ASSISTÉE PAR ORDINATEUR DE PRÉCISION FONDÉE SUR UN ÉCHANTILLONNAGE COMPRESSIF
Abstract:
(EN) A system and method for tomographic image reconstruction using truncated projection data that allows exact interior reconstruction (interior tomography) of a region of interest (ROI) based on the known sparsity models of the ROI, thereby improving image quality while reducing radiation dosage. In addition, the method includes parallel interior tomography using multiple sources beamed at multiple angles through an ROI and that enables higher temporal resolution.
(FR) La présente invention concerne un système et un procédé de reconstruction d'images tomographiques utilisant des données de projection tronquées permettant une reconstruction interne précise (tomographie interne) d'une région d'intérêt, sur la base des modèles de faible densité connus de la région d'intérêt, ce qui a pour effet d'améliorer la qualité d'image tout en réduisant la dose de radiations. Ledit procédé implique, en outre, une tomographie interne parallèle faisant appel à de multiples sources rayonnant sous de multiples angles à travers une région d'intérêt, ce qui permet une résolution temporelle supérieure.
