Abstract
L’invention concerne un dispositif de radiologie comprenant un générateur (12) de rayons ionisants et un détecteur (14) configuré pour détecter les rayons émis par le générateur (12), le générateur (12) et le détecteur (14) étant en regard l’un par rapport à l’autre, le dispositif (10) délimitant un volume utile (60), traversé par les rayons ionisants issus du générateur (12) et reçus par le détecteur (14), le générateur (12) comprenant plusieurs sources (16) réparties le long d’une direction (18) et émettant chacune un faisceau (20) de rayons ionisants essentiellement plat et en forme d’éventail, les sources (16) étant disposées de façon à irradier l’ensemble du volume utile (60) sans translation. L’invention a également pour objet un procédé mettant en œuvre un dispositif (10) selon l’invention et consistant à enchainer successivement l’émission de plusieurs des sources (16).
