Use of three-dimensional printing for simulation in ultrasound education: a scoping review

Abstract

BackgroundThere is a significant learning curve when teaching ultrasonography to medical trainees; task trainers can help learners to bridge this gap and develop their skills. Three-dimensional printing technology has the potential to be a great tool in the development of such simulators. ObjectiveThis scoping review aimed to identify what 3D-printed models have been used in ultrasound education to date, how they were created and the pros and limitations involved.DesignResearchers searched three online databases to identify 3D-printed ultrasound models used in medical education.ResultsTwelve suitable publications were identified for inclusion in this review. The models from included articles simulated largely low frequency and/or high stakes events, with many models simulating needle guidance procedures. Most models were created by using patient imaging data and a computer-aided design software to print structures directly or print casting molds. The benefits of 3D-printed educational trainers are their low cost, reproducibility, patient specificity and accuracy. The current limitations of this technology are upfront investments and a lack of optimisation of materials.ConclusionsThe use of 3D-printed ultrasound task trainers is in its infancy, and more research is needed to determine whether or not this technology will benefit medical learners in the future.

Development of a 3D Printing Strategy to Improve the Level of Abstraction in the Generation of Orthogonal Projections

“…The questionnaire was adapted from satisfaction surveys related to class sessions according to certain authors (Gallagher et al, 2021), based mainly on seeking the opinion of students about the organization, learning activities, evaluations, motivation, didactic tools, and management and accessibility to 3D printing.…”
