- Today the field has opened up remarkably. Computerised tomography or CT-Scans have been developed independently by Nobel prize winning South African physicist Allan M. Cormack and British engineer, Sir George Hounsfield. Positron Emission Tomography (PET), Ultrasound and magnetic resonance imagery (MRI) have added startling facets to radiology.
- What Roentgen discovered a hundred years ago has gone from strength to strength. Following the first paper “On a new kind of Rays (Preliminary Communication)“, he published two more papers on the subject. In April 1900 Roentgen was appointed Professor of Physics and Director of the Physical Institute at the Ludwigo Maximilians University in Munich. In 1901 he received the first Nobel prize in Physics. He retired in 1920, and soon thereafter he breathed his last on February 10, 1921.
