Abstract

In X-ray CT, medical X-ray exposure is the key issue for patients. Recently, low dose exposure is demanded in the industrial X-ray CT. But the dose of X-ray and the image quality are directly correlated. Therefore, research objective is to get high quality images trying to minimize X-ray exposure. Specifically, we reduce the number of X-ray views. We supplied data by using linear interpolation. As a result, we were able to eliminate conspicuous line noise to occur by having reduced the number of views. But different noises extending to horizontal rotatory direction occurred in the method.
