“…Secondly, even when people publish work describing a hacked, recreated ultrasound machine, the individual components can be too expensive for a university laboratory to mass purchase. The audience of such expensive and complex homemade ultrasound scanner is usually the technology-enthusiasts or electronic specialists rather than university students [5].…”

Ultrasound scanner—Teaching tool

Ultrasound imaging, one of the most widely used diagnostic modalities, anchors the fields of medicine, physics, and engineering. In university classrooms, however, ultrasound imaging is often taught passively with a lack of practical element as the clinical machines are not easily available and there are very few alternative teaching tools available on the market. As part of an undergraduate student project, we have developed a teaching toolkit featuring an inexpensive ultrasonic range finder to demonstrate the pulse-echo imaging process. The primary focus is the construction of equipment to enable known pedagogic principles (relating to active learning) to be applied to the subject area of ultrasound. Although operating at an acoustic frequency considerably lower than that employed clinically (and therefore achieving a much lower spatial resolution), the toolkit provides students with large observable effects while keeping cost to the minimum. Completed with an easyto-use user interface and a set of carefully designed supplementary material (https://stacks.iop.org/EJP/42/055703/mmedia) including worksheets and lab technician guide, this toolkit aims to teach students the fundamental principles of ultrasound imaging via hands-on practice. We have designed it to be cheap, easy to set up, and portable. The effectiveness and impact of the toolkit were evaluated by ten undergraduate students who responded in the form of satisfaction questionnaires. To minimise the selection bias, we chose five students who had received no prior university-based instruction on ultrasound and five third-year biomedical engineering students who had learned about the topic previously. They demonstrated a strong interest in using the toolkit for a lab session and described it as user-friendly and highly engaging.

“…Jonveaux has described a highly modular ultrasound imaging platform based on microcontrollers and not using FPGAs altogether. Hence it might be very promising to combine the work of Jonveaux [53] with annular array transducers for high-resolution imaging. Further, the work of Jonveaux [53] provides a very comprehensive reference for researchers interested in low-cost microcontroller-based systems and avoiding the complexities associated with using FPGAs.…”

A wide range of medical devices have significant electronic components. Compared to open-source medical software, open (and open-source) electronic hardware has been less published in peer-reviewed literature. In this review, we explore the developments, significance, and advantages of using open platform electronic hardware for medical devices. Open hardware electronics platforms offer not just shorter development times, reduced costs, and customization; they also offer a key potential advantage which current commercial medical devices lack—seamless data sharing for machine learning and artificial intelligence. We explore how various electronic platforms such as microcontrollers, single board computers, field programmable gate arrays, development boards, and integrated circuits have been used by researchers to design medical devices. Researchers interested in designing low cost, customizable, and innovative medical devices can find references to various easily available electronic components as well as design methodologies to integrate those components for a successful design.

“…In MedTech too a range of open source hardware projects can be found that aim to provide low-cost, adaptable and patient-specific alternatives to proprietary products for private use, e.g. myoelectric prostheses (e-Nable, MyOpen), CT scanners (Tricorder project), echo-stethoscopes (echOpen (Jonveaux, 2017)), infusion pumps (OpenPump), physiological monitoring systems (open-BCI), diabetes treatment (Diabeto, openAPS) (Niezen, Eslambolchilar and Thimbleby, 2016;Moritz, Redlich, and Wulfsberg, 2018). For commercialization of these products, however, approval of authorities of the corresponding markets would be required regarding the safe use of a product.…”

Increasing maturation and dissemination of easy-to-use and affordable means of digital production (e.g. 3D printing), access to these in makerspaces and FabLabs as well as powerful tools and online platforms for virtual and collaborative product design enabled the highly efficient and innovative mode of open source to spill over from software to hardware. Open source technology has enormous potential to spur innovation and enhance technological literacy and thus contribute to socioeconomic and ecological sustainability. Like in software, open source hardware (OSH) projects and online communities have evolved in a broad range of technologies and applications. In these communities, people from all over the world with diverse backgrounds (students, researchers, consumers, users etc.) gather online to jointly develop, revise, improve and freely share hardware designs and documentation. Additionally, people may build, adapt, use and sell physical artefacts based on these designs in accordance with the notion of open source. The (potential) economic impact and value of open source hardware is hard to quantify as contributors usually do not get paid and users do not necessarily buy products from vendors. Nonetheless, value is created as in the case of Linux or Wikipedia. We applied established valuation methods for open source hardware to quantify cost savings and as a result the value of an open source magnetic resonance imaging device (MRI) currently under development by the Open Source Imaging Initiative (OSI 2). Depending on the scenario and the valuation method, we found that savings for healthcare systems from US$1.8 million up to US$222 million per year are possible in the near future making the case for public funding and private investment in open source technology development.
