Abstract

Introduction: Quality and dose factors are very important in radiodiagnostics. To produce a constant radiographic quality, the density and contrast produced must remain constant. There is a rule that aims to produce a constant radiographic quality by adding the exposure value, namely the 10 kV rule. This study was conducted to determine the noise in the computed radiography image with the thorax organ produced by modifying the exposure factor of the 10 kV rule and whether it is still within tolerance.Methods: This quantitative research was conducted with an experimental approach. This is done by taking a series of radiographs that include three exposure factor settings, standard (60 kV, 10 mAs), increased by 10 kV (70 kV, 5 mAs) and lowered by 10 kV (50 kV, 20 mAs). Noise measurement is done by doing ROI in the background area. The exposure index and deviation index values were also recorded as quality and dose references. The data was processed and analyzed by statistical tests.Results: From the statistical test results, there is a significant relationship between kV and noise with a sig (1-tailed) of ,000. Noise on the standard exposure factor has a lower noise than the modified exposure factor with a difference of 0.2. From the quality aspect, the most optimum exposure index and deviation index indicators are in the range of 70 KV and 5 mAs.Conclusion: The results of the statistical test of the relationship of kV to noise obtained at 50 Kv and 20 mAs, 60 kV and 10 mAs gave a significance value of 0.263 and 0.435, while at 70 kV and 10 mAs with Sig. (1-tailed) of .000 which means the relationship between kV to noise is strong because the sig value is below 0.05.

Abstract

Background: In the Thoracic Radiography Technique, applying the use of a grid to control scattered radiation almost never occurs, because the organ that is radiologically examined is classified as soft tissue dominance. Consideration of using grid is very important when the thickness of the thoracic organ exceeds 10 cm, thus potentially increasing scattering radiation which will affect the value of the Contrast to Noise Ratio (CNR). The purpose of this study is to examine the difference between the use of grid and non-grid for the chest radiography techniques in the context of CNR values.Methods: In the study, a hundred healthy patient uderwent the chest posteroanterior (PA) radiographic examination, a half of the total patients was examined with grid whereas the rest without the grid embedded. All the resulted images were analyzed by means of the pixel value measurements at the specific organs of interest (costea and pulmonary tissues) in inside and outside of the lung organs, using 1,5 mm of ROI  from Dicom software. The statistical analysis of the CNR values was performed by comparing the results between the groups.Results: There is a significant difference in the contrast values on the PA radiographs between those using the Grid and without using the Grid (p-value 0.001). The average contrast value on the chest radiograph with Grid is 2283.60, while without Grid is 1878.58. In the Noise values, it also deems significance (p-value = 0.001). The average of the noise values employing the Grid in the technique is 25.32, whereas without Grid is 17.84. In the Contrast to Noise Ratio (CNR), the diference seems to be significant (p-value 0.001). The average CNR radiograph of the PA chest using the Grid is 100.79, while the non-grid is 125.62.Conclusions: The application of the grid in radiography technique gives significant difference in the image results (contrast, noise, and CNR), when compare to the radiographic techniques without the grid. Using the grid in the Technique improve the qPA-thoracic quality of the chest images.
