Mobile x-ray machines:
Injuries caused by the new technologies, such as artillery and the machine gun, required new techniques to treat, and one newly-developed scanning technology, the x-ray machine, was in high demand. However, it was too bulky and fragile to be moved around to treatment centres along the front lines.
The breakthrough came when Marie Curie (who worked on x-rays) developed smaller, sturdier x-ray stations that could be set up in cars and small trucks by October 1914. By 1918, there were 18 “radiologic cars” in operation.
