Abstract

L'invention concerne un appareil de tomographie axiale. Il comprend une source de rayons X et des moyens de détection pour recevoir les rayons le long de plusieurs trajets. Les mouvements de balayage de la source par rapport aux moyens de détection sont effectués en synchronisme avec les battements du coeur du patient examiné, des moyens de détection des battements du coeur étant prévus à cet effet. Application aux diagnostics médicaux par radiographie.
