X-ray irradiation apparatus provided with irradiation range monitor.

摘要

An X-ray irradiation apparatus comprising an X-ray projector (14) for irradiating an object (21) is provided with an irradiation range monitor comprising a light source (11) and a mirror (17) for generating a light beam (LB min ) which is coaxial with the X-ray beam (XB). The light beam is focussed onto the object (21) by means of a focusing lens (19), and the X-ray beam is collimated by means of an X-ray guide tube (15) passing through said mirror (17) and said focusing lens (19).
