Collimator and Beam Alignment Test Tools – Sun Nuclear

Model 161B is a collimator test tool that evaluates the collimator light field congruence. It provides a direct ruled dimension on the radiograph with a normal x-ray exposure. The test tool is a brass plate with centimeter etchings.

Model 162A is a beam alignment tool that provides a simple test of alignment for x-ray beams. The tool is a plastic cylinder and is 16 cm (6.3 inch) high and it has two steel BBs, one at each end.

The two tools combined can visualise x-ray beam misalignments of 1% and 2%, without the need for measuring or calculating.

FEATURES

• Can give a direct ruled dimension on the radiograph because of the centimeter etchings
• Compact and easy-to-use
• The steel BBs are superimposed on the radiograph when everything is aligned
• Bubble level is included so that accurate tests can be performed with ease
