Optical Ultrasound Simulation-based Training in Obstetric Sonography

In their article, Lami Yeo and Roberto Romero introduce a recurrent issue when performing ultrasound examinations in women: the sensitivity of obstetric sonography for detecting fetal anomalies is very low. They argue that ultrasound imaging accuracy is highly operator dependent, so addressing the challenges of becoming a proficient obstetric sonographer could fix a great part of the problem. Hence, they propose simulation-based education learning as an effective solution to overcome those challenges.

Why? Because ultrasound simulators provide training, deliberate practice, and performance evaluation/feedback, resulting in continuous and critical self-evaluation. After describing some of the many types of simulators available, the article discusses the current problems and gaps that exist in ultrasound simulation, including: 1) the high cost of the equipment, technology, and simulation centers; 2) the need to have large spaces available for labs (i.e. a room, center, or facility); and 3) the necessity for an on-site trainer to supervise and evaluate the trainees’ performance.

Finally, the authors introduce optical positioning ultrasound simulation (Volutracer OPUS), the novel high-fidelity simulation system which addresses many of these problems and gaps. How? Due to its unique characteristics, to name a few: 1) it is affordable; 2) it is compact, portable, and personal; and 3) personal ownership of the simulator allows one to practice indefinitely at one’s own individual place!
