NY-101A Collimator and Beam Alignment Test Tools Brass Light Field and X-ray Field Congruence Collimator

• Collimator and Beam Alignment Test Tools comprises a detection plate and a collimation cylinder. Used to evaluate collimator light field and x-ray field congruence plus ensure accurate X-ray beam alignment.
• The NY-101A Collimator Test Tool is designed to evaluate the collimator light field and x-ray field Congruence according to the Center of Devices and Radiological Health(CDRH)specifications. It is constructed of brass so that centimeter etchings on its surface can give a direct ruled dimension on the radiograph with a normal x-ray exposure.
• The collimator test tool is calibrated to show misalignments to within 0.5 cm. The NY-101B Beam Alignment Test Tool provides a simple test of the x·ray beams alignment.
• When used with the Collimator Test Tool,x-ray beam misalignments of 1% and 2% can be visualized without the need for measuring or calculating. The test instrument is constructed of a plastic cylinder 15.5 cm (6.1 in) high.
• There is one lead ball at the bottom and five lead balls at the top, and the center balls are located directly above one another, so that,when level and everything is in alignment,they will be superimposed on the radiograph.

The NY-101A Collimator Test Tool: 32cm * 26cm;

The NY-101B Beam Alignment Test Tool:height 15.5cm, bottom circle diameter 14cm, top circle diameter 12cm.
