Abstract

L'invention se rapporte à une tête d'irradiation à rayons gamma permettant une irradiation panoramique et à un générateur comportant une telle tête d'irradiation. Elle a pour objet une tête d'irradiation comportant une cible en tungstène, de révolution autour de l'axe du faisceau d'électrons accélérés et des moyens de déviation des électrons accélérés pour produire des photons dans plusieurs directions successivement ou simultanément. Lorsque le faisceau d'électrons est dévié dans son ensemble et que la zone d'impact se déplace sur la cible autour de l'axe, l'axe du lobe de rayonnement se déplace de la même manière et permet d'irradier selon un azimuth variable. Application à la radiographie au moyen d'un accélérateur linéaire portatif.
