Ultrasound, called ASDIC, had been used during the second world war to detect submarines. By the 1950s, renamed sonar, it was being applied in the Clydeside shipbuilding industry and elsewhere to identify flaws in metal. Donald, who had arrived in Glasgow in 1954, was fascinated by technology and had the idea that sonar could be adapted to detect flaws in the human body. His first attempts had failed for technical reasons that were obvious to Brown, who changed the Heath Robinson apparatus into something that stood a chance of success.
