CPQR and COMP are committed to supporting high-quality, safe radiotherapy in Canada. Since 2011 they have worked with the medical physics community to develop a suite of Technical Quality Control Guidelines to help radiotherapy centres ensure the minimum performance and safety standards of treatment equipment and technologies. The full suite of TQC Guidelines is available online.

To help radiotherapy programs monitor their adherence to these guidelines, CPQR offers a set of self-audit tools.

The medical linear accelerators and multi-leaf collimators guideline is available here. It is recommended to have it available throughout the self-assessment.

Once you complete the audit and click “Done,” you will receive a certificate to print off and use.

Note: The tool only allows one answer to be marked as correct. However, some alternate answers may still earn 1 point even if they appear as incorrect. For example:

• Greater frequency = more frequent = 1 point.
• Less tolerance = tighter tolerance = 1 point.

Answering N/A will not deduct points from your total score.

This list of tests included in the Linear Accelerators Guideline describes tests that are to be done on a daily basis.

For each test, please indicate whether your program completes it as described and with the frequency, tolerance or action indicated.

Scoring is as follows: 

• Less 0 
• As Described 1
• Greater 1 
• N/A 1

The rationale behind the scoring was:

• Less = does not meet expectations set out in the TQC
• As Described = meets expectations set out in the TQC
• Greater = exceeds expectations set out in the TQC
• Due to software limitations, NA was awarded 1 point so as not to penalize the quiz takers for the line not being applicable to their centre.
