AccuCheck

AccuCheck, defined as a radiotherapy plan quality assurance system, aims to improve the clinical efficiency of offline and online quality control. AccuCheck supports Monte Carlo dose calculation engine, and is applicable to the quality assurance of general offline planning, online adaptive planning and various radiotherapy technology such as photon and proton. AccuCheck is to be used for the quality assurance of offline plans and online adaptive radiotherapy plans, where the TPS Check module is used to check whether the parameters related to treatment plan are within the executable range of the machine; the Dose Check module is designed to use an independent dose calculation engine to re-calculate the original plan before the treatment, and is compared with the dose of the original plan; the Transfer Check module could verify whether errors are occurred during transferring from the TPS system to the accelerator; the Log Check module is used to obtain execution log of each execution of the accelerator, calculate dose through an independent dose calculation engine, and compare it with the dose of original plan; Treatment Summary supports physical dose accumulation of doses executed multiple times for a single plan, which reflect the stability of the accelerator operating, it could at the same time support the reconstruction of log to the fractional images so as to evaluate the daily exposure dose of the patient. AccuCheck provides abundant auxiliary analysis tools, including DVH Graph, Gamma Analysis, Target Coverage, Gamma Pass Rate of each ROI, Dose Statistics, and Clinical Goals Evaluation.
