Abstract


Objectives: This study measured and assessed radiation exposure and the image quality from the acquired image using aluminum filters in an aim to provide basic data for minimizing the exposure dose in X-ray test from dental Digital Radiography system and gaining the optimum image for diagnosis. Methods/Statistical Analysis: The measurement values of CNR and SNR were different depending on the image quality from the acquired image using aluminum filters. Findings: The reduction of entrance exposure dose showed 3.15-25.93 % difference according to the thickness of aluminum additional filters and the conditions of radiation exposure, but it showed consistent tendency regardless of the tube current (mAs) when the tube voltage goes up. In the radiation test for dental areas, the image quality was excellent when higher than 60 kV for the qualitative evaluation and in 0.1 mm according to the difference in added filtration. Improvements/ Applications: This result will be suggested for the data to expect the application of aluminum additional filters and decide the test methods in future dental diagnosis test. It is expected that it will be much utilized for the important basic data to reduce medical radiation exposure.
