The purpose of a quality control program is for technologists to examine and maintain acceptable quality of the X-ray equipment. This kind of program has been operating for decades in the radiographic field and playing an increasingly more prominent role, as technology advances.
The three topics mentioned in our ePortfolio briefly introduced three critical components of a radiographic quality control system which can identify changes in radiographic equipment. These changes may impair the accuracy and efficiency of radiologic diagnosis. Through periodical quality control testing, technologists can request repair or calibration services before harmful consequences can occur.
The EI calibration test consisted of three trials to see if the digital radiography equipment was properly calibrated to give a consistent EI within an acceptable range. The CR erasure was performed to test whether erasure of the CR cassette was sufficient to be reusable. The half value layer test measured the quality of an X-ray beam to evaluate if filtration was adequate. These tests ensure high image quality produced by X-ray equipment. Moreover, they help ensure low repeat rates, which consequently keep the patient dose and adhere to the principles of ALARA.
