Abstract：Objective To explore the key content and implementation process of Eclipse radiotherapy planning system (V15.6)
acceptance test. Methods Using the report of the Canadian Organization of Medical Physicists as a reference, acceptance tests were
performed on CT images, computational model reliability, data transmission and return records, treatment plan validation, and other
safety tests related to the accuracy and reliability of the treatment planning system. Results All the test indexes met the relevant
standards, and the key acceptance results were as follows: the error of each sampling point of CT relative electron density curve was
within 0.02; for the percent depth dose and off-axis ratio data, compared with the measurement results, the deviation of simulation
results of the treatment planning system were less than 2%; the output factor deviation was less than 1% except for the 1 cm×1 cm
field, which was -1.1%; the radiation beam modeling parameter multi-leaf collimator leakage was between 0.0114 to 0.0158, and
the measurement results were less than 0.5%; the γ index was greater than 95% for both two quality control devices of 2D matrix
validation and electronic field imaging system in 2D dose validation when the evaluation strategy was 3 mm position error and 3%
dose deviation; the data transmission, return records, and security tests were normal and effective. Conclusion The Eclipse planning
system in our hospital meets the national standards in terms of accuracy and safety, and can be applied in clinical treatment.
