Objective To discuss the applicability of a quality assurance tool with Medical Imaging Toolkit (MITK) for cone-beam computed tomography (CBCT) images, and to analyze whether it can be used for the quality assurance of CBCT images. Methods The corresponding parameters of CBCT images were recorded with CITK tool and used as the original comparison template when RapidArc was installed, and the CBCT images generated by each QA during the use of the device were measured and identified by means of CITK tool subsequently. Then the parameters obtained, including the CT values of 8 kinds of density plug-in of CATphan 504 phantom as well as the parameters for low-contrast resolution and spacial resolution recognized automatically, were compared with the comparison template to determine whether the CBCT images met the requirements. Results T-test was used in the quantitative analysis. No statistical difference (P>0.05) existed between the CT values obtained during the 5 times of QA yearly inspection and those of the original comparison template. The parameters for low-contrast resolution and spacial resolution recognized automatically satisfied the desired requirements. Condusioii CITK tool can be used for CBCT image quality control.
