Abstract
Apparatus generating a line of light includes a light source, such as an incandescent lamp. A condensing lens is interposed between the lamp and the receiving end of an optical fiber cable for applying the light of the lamp to the cable. The discharge end of the optical fiber cable is flattened into a linear configuration, one or a few fibers thick. The discharge end of the optical fiber cable is coupled to a light beam projector containing a lens focusing and projecting a plane of light. The plane of light forms a line when applied to a patient or other object. A plurality of optical fiber cables and projectors may be coupled to the lamp to provide a pattern of lines.
Claims17
Apparatus for providing a line of light indicative of a property of an X-ray beam on an object comprising:
- an incandescent light source means providing a stationary beam of light;
- condensing lens means for focusing the light;
- and
- optical fiber means comprising an elongated solid bundle of aligned optical fibers having a first end light transmissively coupled to said light source means for receiving the focused light from said lens means, said first end of said optical fiber means having a diameter not greater than the image of said light source applied to said optical fiber means, said bundle of aligned optical fibers having a second end flattened to a width of at least one optical fiber for providing a plane of light forming the line of light indicative of the property of the X-ray beam when applied to the object.
