X-ray has been used in imaging and treatment of cancers since its discovery by Rontgen in 1895. X-rays is part of the electromagnetic radiation spectrum with energies higher than visible light. X-rays are partially absorbed and scattered by tissues when striking the body but those that pass through the body can be detected to form an image of the internal organs. Images taken with one x-ray projection are called planar images. They are mainly good for imaging bony anatomies. Computed tomography (CT) is an imaging procedure that uses multiple X-ray projections to create detailed images of areas inside the body.
Shortly after the use of x-ray for imaging its damaging effect to personnel dealing with x-ray started to emerge. At the same time it was discovered that the same damaging effect can be used for treating cancers. Linear accelerators (Linac) provide high energy x-rays for cancer treatment. Currently there are all kinds of specialized Linacs for treating cancers. However the newest development in cancer treatment is using proton and other particle beams for therapy. In this talk history of x-ray in medical application and the recent application of particle beams in cancer therapy will be presented.
