Abstract
Official abstract text for this publication.
A radiation generating apparatus includes a radiation generating unit and a diaphragm unit that functions as a projector-collimator configured to simulate a radiation field with a visible-light field. The diaphragm unit includes a light source configured to generate visible light, an optical lens configured to control a state of diffusion of the visible light emitted from the light source, and field-limiting blades. The light source and the optical lens are provided between a radiation emission window and the field-limiting blades. The light source is movable into and retractable from a path of radiation generated by the radiation generating unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A radiation generating apparatus comprising: a radiation generating unit configured to generate radiation; and a diaphragm unit configured to limit a radiation field that is formed by the radiation emitted from the radiation generating unit, wherein the diaphragm unit includes a light source configured to generate visible light with which the radiation field is simulated by a visible-light field; an optical lens configured to control a state of diffus…
