Radiology apparatus for example for neurological stereotactic vascular or a reduced size

摘要

The radiology apparatus comprises a source (trx) emitting a radiation x conical, a receiver of radiological images (ii, cv), a chassis (cs) disposed between the x-ray source and the image receiver to receive an object (tt) to be radiographed, and a device for positioning and guiding able to be connected to the chassis and to intercept the x radiation, so as to position and to guide the probes are intended to cooperate with the object. The device for positioning and guiding device comprises first means (cs, rg, gate gc2) forming a retractable guide holes whose respective axes converge towards the focal point (f) of the source when the first means intercept the conical radiation, and a gate of the positioning (g) is retractable to holes.
