X rays are the key technology of hospital imaging departments, and are also used in dentistry, industry, and for security scanning. X-ray technology was the first to allow a doctor to look inside a patient without surgery. Today, hospitals have many other technologies including ultrasound, mri, and nuclear medicine. Yet x-ray technology, including the CT scanner, continues to be a major workhorse and continues to evolve to provide better and more convenient images with acceptable radiation dose. Starting with the inception of x-ray imaging at the close of the 19th century, this talk will trace the development of x-ray technology through today’s computerized machines and on to the future in which we will exploit the wave nature of x rays as well as their particle nature. We will look at where x-ray imaging is likely to go, and introduce some of the people behind the science.
