Radiology device with helically arranged sources and detector

A radiology device comprising a support capable of translational movement about an axis of translation relative to a frame of the device, the support being intended to support an object that is to be imaged, an ionizing-ray generator and a detector configured to detect the rays emitted by the generator, the generator and the detector facing one another, wherein the generator comprises several sources each considered to emit from a focal point, the focal points of the various sources being distributed along a sources axis, in that the detector extends along a detector axis, in that the sources axis and the detector axis extend in the form of mutually intertwined helices about the axis of translation, in that each of the sources emits a substantially flat and fan-shaped beam of ionizing rays, in that the device further comprises a collimator having, facing each source, a slot configured to obtain the fan-shaped beam and produced in a plane of the collimator that is parallel to the axis of translation, in that the collimator extends mainly along a collimator axis parallel to the sources axis, in that the slots are not secant and in that the slots each extend mainly along a curve portion defined in the plane of the collimator and in that the projections, perpendicular to the collimator axis, of curve portions, corresponding to consecutive slots, onto the collimator axis, have a part in common.
