Abstract
A visible light projection indicator for a dental x-ray imaging apparatus, including a casing (2), one end of the casing (2) detachably affixed to a beam-limiting cone (3) in the dental x-ray imaging apparatus, the other end thereof provided with a light exit aperture; a visible light source (1) positioned in the casing (2) and configured to be able to emit visible light; the casing (2) affixed to the beam-limiting cone (3) so as to form a light passage so that visible light emitted from the visible light source (1) is able to travel along the light passage and exits from the light exit aperture. A method of using a visible light projection indicator for a dental x-ray imaging apparatus, including the steps of: affixing the visible light projection indicator to a beam-limiting cone (3); activating at least one visible light source (1) to cause visible light to be emitted from a light exit aperture of the visible light projection indicator; according to a light field (6) of the visible light, adjusting a distance and an orientation of the beam-limiting cone (3) from and with respect to an object to be imaged so that the visible light is aligned with a center of an area (5) to be ima…
