The Condition of the Exposed Factor (KV, MA.S) on the Radiography after the Adjustment of the Calibration of the Mobile Aircraft

Introduction

The quality of radiographic images is heavily dependent on the accuracy of the exposure factors, particularly the tube voltage (KV) and milliampere-seconds (MA.S). Any discrepancy between the set and actual tube voltage can significantly affect the quantity of X-rays and the overall quality of the radiographic image. In this study, we aimed to investigate the condition of the exposed factor (KV, MA.S) on the radiography after the adjustment of the calibration of the mobile aircraft.

Background

The Mobile Meditronic X-ray unit is a widely used device in medical imaging, particularly in radiography. However, the accuracy of the exposure factors, including KV and MA.S, is crucial for achieving high-quality radiographic images. A previous study revealed that there was no basic quantitative data regarding the condition of the exposure factor after calibration on the device. Therefore, this study aimed to determine the adjustment method of the tube voltage and the results of the adjustment as quantitative data for evaluation.

Methodology

This study employed a quantitative research approach with a participatory observational method. Data collection was done through testing the output of the X-ray aircraft tube voltage using a KV meter measuring device. The test was carried out at six different levels of KV (50 kV, 60 kV, 70 kV, 80 kV, 80 kV, and 90 kV) with a fixed MAS value of 10 MAS. The measurement data obtained were then processed and analyzed in the form of tables and graphs to facilitate drawing conclusions.

Results

The results of the study showed a voltage deviation at each level of KV tested. The detected deviations were as follows: 50 kVs experiencing deviations of 3.96%, 60 kV by 2.98%, 70 kV by 2.27%, 80 kV by 3.25%, and 90 kV by 3.14%. Although there were these deviations, the overall KV output value generated from 50 KV to 90 KV was still within the permitted tolerance limit, which is ± 10%.

Discussion

The importance of data obtained from this study is to ensure the quality and safety of radiographic procedures carried out. The above deviations can give an indication that even though the tool functions properly, attention is still needed in the calibration process and adjustment. Good radiographic quality is very dependent on stability and voltage accuracy supplied to X-ray tubes.

In the context of radiological practice, knowing and understanding the value of this deviation allows medical staff to carry out the necessary corrective actions. It also has the potential to reduce the risk of diagnosis errors due to unrepresentative images. In other words, information collected is not only useful for research, but also very applicable in everyday clinical practice.

Conclusion

In conclusion, the right calibration of the Meditronic X-ray Mobile Unit X-ray aircraft at the Fauzi Rontgen Clinic Medan is a key factor for achieving quality radiographs. This study also opened a way for further research to improve calibration standards and accuracy in the use of medical devices in the future.
