Understanding the Basic Principles of Computerized Tomography

초록

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.
