The Development of Web Application and Projection System for Assisting Patients with Chest X-Ray Positioning

Chest X-ray imaging helps doctors assess the severity of infectious diseases. Radiologic technologists directly involved in chest X-rays are at risk of exposure while preparing patients for imaging. To address these issues, we developed the XBOT web Application and projection system to assist patients with chest X-ray positioning. The XBOT web application and projection systems have been developed to provide bilingual guidance for chest X-ray positioning, posteroanterior, and lateral view. The systems use Thai and English instructions and video demonstrations. We produce engaging videos for projection systems that effectively demonstrate the proper positioning on a bucky wall stand. User experience and satisfaction with the positioning systems were evaluated. In this study involving 13 volunteers, the average time for chest X-ray positioning was 11.52 seconds for the right lateral, 15.22 seconds for the left lateral, and 22.90 seconds for the PA view. The study demonstrated the effectiveness of the XBOT system in chest X-ray positioning. The right lateral view achieved the highest average score of 5.00 ± 0.00 points, followed by the left lateral view at 4.77 ± 0.42 points and the PA view at 4.23 ± 0.42 points. Satisfaction with the XBOT Web Application and Projection System resulted in an overall score of 4.25 ± 0.67, indicating general satisfaction with its performance. The results indicate precise positioning, suggesting that the XBOT web application and projection systems may reduce staff workload. Minimizing contact between patients and radiologic technologists may also lower the risk of infection within the hospital.
