Abstract：Objective To find the gap between the new domestic accelerator and the import accelerator, and to better use XHA600E
accelerator for clinical treatment, we performed a systematic test with the technical indicators of XHA600E digital accelerator and
a comparative analysis between the Unique accelerator and XHA600E accelerator in the key parameters. Methods Firstly, the
mechanical parameters, ray parameters, MLC parameters and EPID performance of the XHA600E accelerator were tested by using
tools such as spirit level, coordinate paper, three-dimensional water tank, rinse-free film and Las Vegas phantom according to the
national standard GB/T 19046 “medical electron accelerator acceptance test and periodic inspection procedures”. Then the key
parameters include the accuracy of isocenter, ray quality, field flatness and symmetry of Unique accelerator were tested. Finally, two
equipment test results were compared and evaluated. Results The technical indicators of XHA600E accelerator were all within the
scope of error requirements. Two devices had little difference in the key parameters such as accuracy of isocenter, ray quality, field
flatness and symmetry, and Unique overall was superior to XHA600E. Conclusion Compared with the previous generation of 600D
model, XHA600E has greatly improved in hardware and software performance, which narrows the gap with the import accelerator.
However, there is still a lot of room for improvement in 3D image verification and dose verification.
