Uniformity Test and Slice Thickness Suitability Using ACR 464 Phantom on CT-Scan 16 Slice Aircraft Quality

Introduction

The accuracy and value of CT Number uniformity, as well as the suitability of the thickness of the slice, are crucial factors in determining the quality of CT-Scan images. In this study, a uniformity test was conducted and the suitability of the thickness of the slice on the CT-Scan image using ACR 464 Phantom. The main objective of this study is to assess the accuracy and value of CT Number uniformity, as well as assess the suitability of the thickness of the slice, as well as evaluating the impact of the thickness of the slice on the CT-Scan image.

Methodology

The measurement results show that the accuracy value of the CT Number at the thickness of the 1.0 mm slice is -3.5, 2.0 mm is -3.8, and 4.0 mm is -3.4, with the pass limit ≤ ± 4. Meanwhile, the accuracy value of the CT Number uniformity at the thickness of the 1.0 mm slice is -1.1, 2.0 mm is -1.7, and 4.0 mm is -0.8, with the passway of passing ≤ ± 2. In addition, the results of the measurement of slice thickness show that the value for each slice thickness is 1.0 mm = 0 mm, 2.0 mm = 0 mm, and 4.0 mm = 0 mm, with a pass limit of ≤ 0.5 mm. All of these values are below the specified tolerance limit and meet BAPETEN regulatory standards No. 2 of 2018 concerning the CT-Scan X-Ray Aircraft Suitability Test in Image Quality Parameters.

The Importance of ACR 464 Phantom

The use of ACR 464 Phantom in this study is very important because it allows researchers to evaluate image quality objectively. This phantom is specifically designed to test various aspects of the CT-Scan system, including uniformity, accuracy, and slice thickness. Slice thickness is a crucial factor that affects image quality and can directly affect medical diagnosis.

Impact of Slice Thickness on Image Quality

With slice thickness variations, researchers can observe how this difference affects the resulting image results. Smaller slice thickness usually gives a higher resolution, but also increases the dose of radiation received by the patient. Therefore, it is important to find a balance between image quality and patient safety. The results of this study indicate that all slice thickness tested is within the specified tolerance limit, so that it can be indicated that the CT-Scan aircraft works according to applicable standards.

Regulatory Standards and Patient Safety

Furthermore, it is important to notice that Bapeten regulations provide clear guidelines regarding the suitability and security of CT-Scan aircraft. Comply with this standard will not only guarantee the quality of the image produced, but will also protect patients from potential health risks due to unnecessary radiation exposure. Therefore, the implementation of uniformity tests and regular compatibility is a must be done by health facilities to maintain the quality of the medical services they provide.

Conclusion and Future Research

Through this research, it is expected to contribute to improving the quality of medical diagnoses and patient trust in developing medical imaging technology. Knowledge obtained from the results of this test can also be a reference for further research in the field of imaging technology.

Recommendations

Based on the results of this study, it is recommended that health facilities conduct regular uniformity tests and compatibility checks to ensure the quality of their CT-Scan images. Additionally, researchers should continue to explore the impact of slice thickness on image quality and develop new methods to improve the accuracy and value of CT Number uniformity.

Limitations and Future Directions

This study has several limitations, including the use of a single CT-Scan system and the limited number of slice thickness tested. Future research should aim to investigate the impact of slice thickness on image quality using multiple CT-Scan systems and a wider range of slice thickness.

Conclusion

In conclusion, this study demonstrates the importance of uniformity tests and slice thickness suitability in ensuring the quality of CT-Scan images. The use of ACR 464 Phantom allows researchers to evaluate image quality objectively and provides a clear understanding of the impact of slice thickness on image quality. The results of this study indicate that all slice thickness tested is within the specified tolerance limit, and the implementation of uniformity tests and regular compatibility is a must be done by health facilities to maintain the quality of the medical services they provide.
