Prof Peter Wells's 55 years developing ultrasound
A Cardiff University professor who helped develop medical ultrasound scans is seeking further breakthroughs after winning a top scientific accolade.
Peter Wells is being honoured with the Royal Academy of Engineering award, first won by Sir Tim Berners-Lee, who invented the worldwide web.
Prof Wells said his commitment to research was unwavering.
He is helping to develop a new type of CT scanning which is likely to be used for ultrasonic breast screening.
He is also in the early stages of trying to develop a much faster form of ultrasound scanning.
An ultrasound scan uses high frequency sound waves to create an image of the inside of the body.
"I hope to go on being involved forever. It's the interest of the work - you don't do it for the money," Prof Wells said.
He will receive the Sir Frank Whittle Medal, named after the jet engine engineer, on Monday.
He told BBC Radio Wales' Oliver Hides he started working when the technology was in its infancy.
