Thomas Graham Brown (b. 1933), engineer who developed the first practical medical ultrasound machine, to pioneer ultrasound diagnoses in obstetrics and gynaecology.
Tom Brown was responsible for converting the idea of using ultrasound scanning for medical purposes into a practical proposition.
Tom Brown trained as a Research & Development Engineer with Kelvin & Hughes Ltd, the Glasgow scientific instrument company founded by Lord Kelvin. He worked on the development of ultrasound equipment for testing welds in large pressure vessels. When he was 23, he learned that Professor Ian Donald was attempting to use one of the firm's Flaw Detectors to distinguish between fibroids and cysts and he offered to help. It became clear to Tom that some form of pictorial imaging was needed and he believed that it might be possible to make radar-like images of internal organs. Brown conceived and designed the low cost prototype which was to be the first direct contact ultrasound scanner, and had it built onto a borrowed hospital bed table in the firm's workshops. The company applied for patent protection with Brown as Inventor.
The prototype was made available to Professor Donald, assisted by Dr John MacVicar, in early 1957. They quickly realised its potential, and began exploring its clinical applications, which led to the Donald, MacVicar and Brown Lancet paper in June 1958, less than two years after the initial contact. Kelvin & Hughes insisted that the firm, including Brown, should remain in the background and encouraged Donald to become the public face of the project.
