Introduction

Thorax examination using radiographic technique is an essential step in the diagnosis of various lung diseases. The quality of the image obtained from this examination plays a crucial role in determining the accuracy of the diagnosis. In recent years, the use of computed radiography (CR) has become increasingly popular due to its ability to produce high-quality images with minimal radiation exposure. However, the choice of radiographic technique, including the use of high voltage techniques (high KV) versus standard voltage techniques (standard KV), can significantly impact the quality of the image obtained.

Background

Computed radiography (CR) is a digital imaging technology that uses a photostimulable phosphor plate to capture images. This technology has several advantages over traditional film-based radiography, including improved image quality, reduced radiation exposure, and increased efficiency. However, the choice of radiographic technique, including the use of high voltage techniques (high KV) versus standard voltage techniques (standard KV), can significantly impact the quality of the image obtained.

Research Methodology

In this study, a patient who underwent a thorax examination in an anterior postero (PA) position was used as the object. For the shooting process, a CR system from Kodak was used, which has proven its quality. Image collection was done with different arrangements; high techniques utilized 2.2 mas, while standard techniques used 8 mas for 66 kV and 6.3 MAS for 85 kV.

Evaluation Results

The evaluation results from thorax imagery show that high voltage techniques produce better image quality compared to standard voltage techniques. The image produced with high techniques shows more details and sharper contrast, making it easier for doctors to diagnose lung disorders. The results of this study are consistent with previous studies that have shown that high voltage techniques (high KV) produce better image quality compared to standard voltage techniques (standard KV).

Additional Analysis and Explanation

The selection of radiographic techniques, both high and standard voltage, is very influential on the quality and interpretation of medical images. High voltage techniques (high KV) are generally used to minimize radiation received by patients and increase X-ray penetration of dense tissues, such as the lungs. In practice, the image of this technique provides a more informative visualization, especially in medical conditions that require in-depth analysis such as pneumonia, tumors, or chronic obstructive pulmonary disease (COPD).

On the other hand, standard voltage techniques (standard KV) although it may be enough for many indications, often does not provide the details needed for complex diagnoses. However, this technique is more often applied in conditions where radiation must be minimized or when very high details are not needed.

Comparison of High Voltage Techniques and Standard Voltage Techniques

The results of this study show that high voltage techniques (high KV) produce better image quality compared to standard voltage techniques (standard KV). The image produced with high techniques shows more details and sharper contrast, making it easier for doctors to diagnose lung disorders. The results of this study are consistent with previous studies that have shown that high voltage techniques (high KV) produce better image quality compared to standard voltage techniques (standard KV).

Conclusion

In the context of thorax examination using computed radiography, the use of high voltage techniques shows superior results compared to standard voltage techniques. This study provides valuable insight for radiology practitioners to consider appropriate radiographic technical options based on diagnostic needs and patient conditions. Through a better understanding of the comparison of this technique, it is expected to improve the quality of health services and the results of diagnosis for patients.
