Topic
Medical Imaging
Uncover how physics helps doctors see inside the human body without surgery. From the earliest X‑rays to advanced scans like CAT and PET, this topic explains how different imaging technologies work and how they rely on physical principles to form diagnostic images.

From Röntgen’s X‑Ray to Modern Medicine
“I have seen my death” – Anna Rontgen – 1895 (the banner image is the first X-ray image, which shows her left hand – spot the wedding ring?)
Wilhelm Rontgen would be awarded the first Nobel Prize for Physics in 1901, but like the Curies (Marie, Pierre and Irene) could have been justified in being awarded the prize for Medicine instead. Following X-rays and radiotherapy, many discoveries in physics have led to applications in medicine.
