Title
(EN) X-RAY COLLIMATING AND BODY SHIELDING ACCESSORY INSTRUMENT
(FR) INSTRUMENT ACCESSOIRE SERVANT A PROTEGER LE CORPS ET A COLLIMATER LES RAYONS X
Abstract
(EN)
The invention is a beam limiting instrument (1) comprising a unit (3) having a frame (19) defining the perimeter about an aperture (20), and a manually adjustable rack (2) connected to the frame (19) for supporting the unit (3) with its aperture disposed between a source (4) of X-rays (6) and the body of a patient (5). Radio-opaque flexible panels (21) depending from the frame (19) are pivotable relative to the aperture (20) to collimate and limit X-rays (6) issuing from the source (4) through the aperture (20) to a particular area of the body of the patient (5). Translucent ports along lower edges of the panels serve to provide upon a photographic film (7) below the patient a scale indication of the area of the body of the patient (5) subjected to the X-rays (6).
(FR)
L'invention concerne un instrument (1) de limitation de faisceau constitué par un ensemble (3) possédant un cadre (19) définissant le périmètre autour d'une ouverture (20) et un bras articulé (2) réglable manuellement relié audit cadre (19) afin de supporter l'ensemble (3), dont l'ouverture se trouve entre une source (4) de rayons X (6) et le corps d'un patient (5). Des panneaux souples (21) impénétrables au rayonnement, accouplés au cadre (19), sont rotatifs par rapport à l'ouverture (20) afin de collimater et de limiter les rayons X (6) émis par la source (4) à travers l'ouverture (20) vers une zone déterminée du corps du patient (5). Des orifices translucides le long des bords inférieurs des panneaux servent à produire sur une pellicule photographique (7) située au-dessous du patient, une indication à l'échelle de la zone du corps du patient (5) soumise aux rayons X (6).
