From the early days of hospital care and the inception of the NHS in 1948, the field of Medical Physics has driven advances in technology and aided innovations in healthcare. In 1901, the first Nobel Prize for Physics was awarded to Wilhelm Roentgen for his discovery of X-rays in 1895. Like many physicists, Marie Curie operated mobile X-ray imaging units during the First World War, training the first Radiologists, which contributed to saving millions of lives. Medical Physicists are key workers within the healthcare workforce, supporting day-to-day delivery and improvements in patient care. It is important that Healthcare Scientists are proactive in their own personal development, ensuring their skills and knowledge are kept up to date. Specialist skills and knowledge need to be continually refreshed and maintained through adopting the principles of Continuous Professional Development. All Clinical Scientists work closely with medical devices. Medical devices and health technology are integral to all aspects of patient care.
