Abstract:
Objective To explore the value of Computed Radiography(CR) in quality control for the medical linear accelerator. Methods By using both CR and autoradiography film respectively, we tested the alignment of light fields with radiation fields, colimator rotation with center, couch rotation with center and multi-leave colimators(MLC) position accuracy of medical linear accelerator. Each tests were carried out ten times repetitive colection. Then compared the differences between this two methods.Results There were no significant difference between CR and autoradiography film in the same grup(P>0.05).Conclusion CR can be used in quality control for the medical linear accelerator since it can meet quality control requirements of radiotherapy.
