Technology Marketing Summary

Obtaining a usable x-ray image means that the technician must align the x-ray beam, collimator, and target properly, which often means taking several test radiographs, resulting in lost time and a waste of materials. The Leha'ir system uses a focused, visible light to indicate the spread of an x-ray beam. The light assists in aligning the x-ray generator with the target to achieve the required radiographic coverage. An indication system and electrical lockout are used on the x-ray generator to protect the light from the harmful x-rays and ensure that the light beam is retracted prior to exposing the film.

Description

The system allows for a simple and safe visual alignment method. The frame is hinged/sliding and mounted to the face of the x-ray generator. The light is high-intensity LED light, which illuminates the area of the projected radiation beam. The interlock switch prevents the x-ray generator from operating while the operator is aligning.

Benefits
  • Aids technician in radiographic setup to ensure coverage with significantly reduced rework

X-RAY BEAM ALIGNMENT DEVICE AND METHOD
The present invention provides a bright, focused visible light source that is part of a visible light alignment assembly that is coupled to an X-ray generator. The visible light source projects a bright, focused visible light beam from the X-ray generator through a collimator and object or part to be radiographed and to a detector or film, just as a subsequent X-ray beam eventually is. This allows the operator to quickly and easily visually assess the eventual position and coverage or spread of the X-ray beam and align the X-ray generator, collimator, object or part to be radiographed, and/or detector or film, with a minimum of test radiographs.
