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.

Computed tomography is highly evaluated for its diagnostic excellence through rapid technological progress. Among them, coronary CT, which diagnoses heart disease, is helping to keep the golden time of heart disease treatment. Recently, dual-energy CT, which is widely used in heart and uric acid stones, not only increases the usefulness of the examination, but also decreases the patients exposure dose. In the future, multi-energy computed tomography is expected to expand the development of new technologies such as photon counting detector, fusion with 3D printing technology, machine learning analysis in medical imaging, and introduction of artificial intelligence technology.
