Allan Mc Leod Cormack is a South African physicist born in Johannesburg in 1924. He developed an interest in radiography which led him to establish the theoretical foundations of CT.
Allan’s work led to the invention of the very first medical X-ray scanner, which was developed in 1972 and marketed in 1975. The medical scanner can detect anomalies that are not visible on conventional radiographs or during an ultrasound.
Allan Mc Leod Cormack obtained the Nobel Prize in physiology or medicine in 1979.
