How can X-ray collimator errors or malfunctions be detected and rectified?

X-ray collimator errors or malfunctions can be detected and rectified through the following steps:
Visual Inspection: Start by visually inspecting the collimator for any obvious physical damage or misalignment.
Functionality Testing: Check if the collimator is functioning properly. This can be done by observing the collimation light or by conducting a test exposure with a phantom or a test object. Ensure that the collimator blades are moving smoothly and consistently without any unusual noise or resistance.
Accuracy Assessment: Measure the accuracy of collimation using a collimation tool, such as a collimator tester or an alignment test phantom. This allows you to assess if the collimator blades are aligning correctly and providing the desired field size and shape.
Radiation Safety check: Verify that the collimator is adequately attenuating the radiation outside the primary beam. Use a radiation survey meter to measure radiation levels outside the collimated field, focusing on areas where radiation leakage could occur, such as around the edges or between the blades.
Error Documentation: If any errors or malfunctions are detected during the above steps, record the observations, measurements, and any abnormal behavior of the collimator for further analysis.
Contacting Service or Technical Support: If the collimator issues cannot be rectified by conventional troubleshooting, it is necessary to contact the manufacturer’s service or technical support. They can provide guidance on potential solutions or arrange for a service technician to inspect and repair the collimator.
Preventive Maintenance: Regular preventive maintenance, including cleaning, lubricating, and adjustments, should be performed according to the manufacturer’s recommendations to ensure the long-term accuracy and reliability of the collimator.
It is crucial to follow appropriate safety protocols and consult with a qualified professional or the manufacturer for specific guidance when dealing with X-ray collimator errors or malfunctions. Whatsapp:+86 18953679166. Email: service@newheek.com
