Abstract：Objective To explore the acceptance process of Halcyon 2.0 linear accelerator preloading typical ray data in treatment
planning system (TPS), to ensure that test results meet clinical treatment requirements. At the same time, to verifie the reliability of
pre-installed data. Methods According to the characteristics of Halcyon 2.0 accelerator and the factory manual, the conventional
accelerator and TPS acceptance practice, combined with the domestic and foreign acceptance standards, quality control was
conducted from three aspects: clinical commissioning of linear accelerator, TPS acceptance and patient verification test. Meanwhile,
the measured dosimetric parameters were compared with pre-installed data of our hospital’s accelerators and external hospital.
Results The mechanical properties and image quality of this Halcyon linear accelerator met the factory standard. The maximum dose
depth of our hospital was 1.19 cm (the pre-installed data: 1.30 cm, external hospital: 1.40 cm), which was within (1.30±0.20) cm.
The percentage depth dose (PDD) was 62.97% at 10 cm depth (the pre-installed data: 63.00%, external hospital: 63.50%), which was
within 63.0%±1.00%. The PDD and off axial ratio (OAR) of 10 cm ×10 cm field had good consistency with the data of the preinstalled
data. Radial and lateral OAR and symmetry of 28 cm×28 cm field at off-axis 10 cm met factory standards. Conclusion The
measurement data of Halcyon 2.0 linear accelerator is in good consistency with the pre-installed data of TPS and the measurement
data of external hospital. The clinical test results all meet domestic and foreign acceptance standards and can be put into clinical use.
