Positioning the X-Ray Generator with CS 2200
The scissor arm allows you to accurately position the generator for any type of exposure. The beam-limiting device maintains a distance of at least 20 cm (8 in.) between the focal spot and the skin, which allows you to use either the paralleling or the bisecting technique.
Paralleling Technique
The positioning tool used in the paralleling technique allows you to align the beam and the image receptor. An appropriate collimator reduces the dosage by limiting the surface exposure.
Bisecting Technique
When using the bisecting technique, do not use a rectangular collimator. This limits the risk of X-ray beam and image receptor misalignment.
