DIGITAL CONSOLE CONTROL SIMULATOR BASED ON NEXTION FOR MOBILE X-RAY CONDENSATOR DISCHARGE

Abstract

As a safe and radiation-free educational medium, this study developed a Nextion-based digital console control simulator for mobile X-ray systems using the capacitor discharge principle. The simulator is intended to simulate capacitor charging and discharging and interactively control exposure parameters such as voltage (kV) and time (mAs). The author used a literature study to find theoretical bases, research reports, books, Standard Operating Procedures (SOPs), and national and international journals. Testing was carried out on 26 protocols consisting of four body parts, namely (1) the body, (2) the cranium or spine, (3) the upper back, and (4) the lower back. The results showed that the system was capable of measuring voltage with an average error of 1.05 volts, a percentage error of 1.46%, and an average system accuracy of 98.57%. The average exposure time was ±0.01 seconds, and the average system accuracy was 99.08%. An informative Nextion-based interface was used for this system. The kV and mAs values can be set in the range of 30 to 200 kV and 2 to 30 mAs. The results of this study indicate that simulators can be used as technical learning tools in radiology because they combine ease of operation, safety, and accuracy in the practice-based education process.
