The Quick Quality Control and Calibration Method for the Laser-Assisted Positioning System of Elekta Medical Linear Accelerator
With the introduction of the concept of precision radiotherapy and the continuous innovation and rapid development of radiotherapy technology,the demand for precise positioning of radiotherapy in clinical practice is constantly increasing.The laser-assisted positioning system plays an indispensable role in the positioning,placement,and pre-treatment repositioning process of radiotherapy,and its accuracy directly affects the treatment effect of patients.Therefore,to ensure the accuracy and effectiveness of the treatment process,the quality control(QC)and calibration methods for the laser-assisted positioning system must be mastered by radiation therapy physicists.In this study,a method for rapid QC and calibration of Medical Linear Accelerator Laser-Assisted Positioning System using Penta-Guide phantom was proposed,aiming to provide practical reference for radiation therapy physicists.With a rapid QC and calibration process of approximately 2 minutes,the rapid QC and calibration of the daily bed levelness,field consistency,and laser lamp accuracy of the linear accelerator,as well as real-time calibration of the laser lamp offset,could be completed.
