Abstract: Background: Hands-on training in point-of-care ultrasound (POC-US) should ideally comprise bedside teaching, as<br>well as simulated clinical scenarios. High-fidelity phantoms and portable ultrasound simulation systems are commercially<br>available, however, at considerable costs. This limits their suitability for medical schools. A Linux-based software<br>for Emergency Department Ultrasound Simulation (edus2TM) was developed by Kulyk and Olszynski in 2011. Its feasibility<br>for POC-US education has been well-documented, and shows good acceptance. An important limitation to an<br>even more widespread use of edus2, however, may be due to the need for a virtual machine for WINDOWS® systems.<br>Our aim was to adapt the original software toward an HTML-based solution, thus making it affordable and applicable<br>in any simulation setting.<br><br>Methods: We created an HTML browser-based ultrasound simulation application, which reads the input of different<br>sensors, triggering an ultrasound video to be displayed on a respective device. RFID tags, NFC tags, and QR CodesTM<br>have been integrated into training phantoms or were attached to standardized patients. The RFID antenna was hidden<br>in a mock ultrasound probe. The application is independent from the respective device.<br><br>Results: Our application was used successfully with different trigger/scanner combinations and mounted readily into<br>simulated training scenarios. The application runs independently from operating systems or electronic devices.<br>Conclusion: This low-cost, browser-based ultrasound simulator is easy-to-build, very adaptive, and independent<br>from operating systems. It has the potential to facilitate POC-US training throughout the world, especially in resourcelimited<br>areas.<br><br>Keywords: Ultrasonography, Point-of-care systems, Simulation training
