Carried out Kilovoltage test, mR/mAs output test, Light filed/Beam alignment test, Half value layer test. Most of test result are appeared that failure rates of clinic is higher than hospital one. Therefore, we should lower failure rates through regular quality control and make environment which can get high quality image.
