Quality control tests and procedures of computed tomography device according to international standards

Quality control tests are the process of reviewing all parameters belonging to the system of the device with the most general definition. Thanks to the quality control tests, changes in the performance of the devices are easily detected. Regular quality control tests are very important in order to report the problem correctly when the device is serviced. The purpose of quality control tests is to obtain many quantitative measurements and to check the compliance of the established system with international standardization. Based on the internationally recognized specification document, a comparison is made with the reference values in these documents.. quality of the images obtained from the devices used in medicine is very important for the correct diagnosis of diseases. High image quality depends on correct and periodic quality control tests. Quality controls of device parameters are repeated periodically while using the device. Thus, while the continuity of the periodic controls of the devices is carried out in a healthy way, it is aimed to reflect the X-ray distribution on the patient to the images in an accurate and quality manner. If quality control tests are not performed regularly, deterioration occurs in the homogeneity of the images. In this thesis, the quality control tests of the computed tomography device will be evaluated by taking international standards and the procedures in this process will be presented within the scope of this thesis.
