Ludlum Medical Physics Model L-661-662

  Collimator/Beam Alignment Test Tool

Introduction

The Ludlum Model L-661-662 Collimator/ Beam Alignment test tool provides the necessary verification of the proper congruence of the collimator light field and the x-ray beam. Mis-alignment of the collimator may cause key portions of the image to be missing from the radiographic image.

The beam alignment (cylinder) portion of the test tool confirms that the central ray is perpendicular to the image receptor. Improper beam alignment will cause a distorted radiographic image.

The test tool is easy to use and readily identifies misalignments and improper angulation of the x-ray tube.
