Researchers at Switzerland's Federal Institute of Technology in Lausanne are developing an inexpensive, easy-to-use radiology machine that's functional in sub-Saharan Africa and elsewhere in the developing world where conditions are pretty rough. They created the EssentialTech program to develop a device that relies on both X-ray and ultrasound tech, the Swiss Broadcasting Corp. reports. Their goal is to have a prototype in play within two years, and the team will pursue development work, in part, with engineering researchers at a university in Cameroon. The FIT's pursuit of "frugal innovation" in diagnostic imaging comes as the Bill and Melinda Gates Foundation and others work to come up with medical tools and point-of-care diagnostic tests for the developing world.
