Abstract

This research aimed to review the density of radiographs with different variations of tube currents. It was conducted at the Radiology Laboratory of Al Islam Polytechnic of Bandung. This study is an optimization of the results of the X-ray machine examination in order to produce good quality images with the smallest possible radiation given to the patient within a safe limit value. Exposures were carried out on the step wedge with different tube currents of 5 mAs, 8 mAs, 10 mAs, 12.5 mAs, and 80 kV voltage, as well as the exposure time of 0.05 second which was set as a constant variable. The measurement results showed that the greater the tube currents were, the greater the measured density value would be. In accordance with the thickness of the material passed by the X-rays, the thicker the material was, the smaller the value of the measured density would be. Furthermore, among different selected tube currents, the tube current value of 5 mAs became the optimal value. It was indicated by the coefficient of determination between the tube current and the radiographic density value of 0.9842. However, other tube current variations were also more than 0.90. Consequently, it can be concluded that current values will greatly affect the density value of radiographs.

Abstract

The provision of exposure factors is the key to producing quality radiographs in providing accurate anatomical information. This study aimed to determine the difference in anatomical information from radiographs of cranium examination as an indication of radiograph quality in the selection of several exposure factors. The study was conducted at Hermina Arcamanik Hospital in April 2024. A phantom cranium was used as the object, and the exposure factor was set at a variation of the tube voltage value 60-80kV with the tube current value fixed at 20mAs. The radiographs were evaluated for anatomical details and analyzed through the Friedman test. The results showed that the anatomical information for each tube voltage value was 4.18 for 60kV, 3.91 for 65kV, 3.50 for 70kV, 2.27 for 75kV, and 1.14 for 80kV. The value of 60kV/20mAs has the highest mean rank value indicating that this exposure factor provides the most optimal anatomical detail
