A system for the quality audit of treatment dose delivery in radiotherapy.
Treatment planning is a process requiring the cooperation of a number of different staff groups. The possibility for error is well recognised and quality control procedures are necessary to ensure that the chances of errors in planning leading to incorrect treatments are as low as possible. An audit system is described which is based on the calculation of the dose delivered to the patient using the parameters set for treatment as input data. The calculated dose is compared with the prescribed dose and errors greater than a defined limit are flagged. During a period of 19 months during which this audit procedure has been operating a total of 14 errors in excess of 5% were discovered and corrected, this is approximately 0.5% of the total number of plans checked.
