The electromagnetic radiation therapy is a typical treatment method for treating human body cancer. During the past 100 years, there has been a rapid change in the progress of medical technology, and there have been many developments in the last ten years. Computed tomography was introduced for radiation therapy, and Three-dimensional conformal radiation therapy was started through image reconstruction techniques. Through intensity-modulated radiation therapy which examines the radiation intensity from the same plane in another way, more complex and detailed treatment became possible. In addition, accurate treatment became possible via image-guided radiation therapy which increases the reproducibility of the patients position by using images acquired with the treatment equipment. Recently, with the advent of new equipment through the fusion of magnetic resonance imaging equipment and therapy equipment, it will give much help to radiation therapy. Such changes are expected to have many developments in the field of radiation therapy in the future.

In computed tomography, X-ray attenuation occurs by various organs that make up the human body. The attenuated data is used to create an image that we can observe with our eyes. In the process, the patient is exposed to radiation that cannot be avoided. Recent research is trying to improve the image quality while reducing the radiation exposure dose to the human body. Therefore, reconstruction algorithms of various methods are newly introduced. In the future, along with the development of a reconstruction algorithm, it is expected that the development of a detector that realizes an image of excellent quality with a small dose is expected.
