Abstract :
In this paper, we propose a limited-view computer tomography(CT) image reconstruction method that reduces the scan times and X-ray dosages in the semiconductor industry. To reduce streak artifacts, which are caused by an insufficient number of views, we study the sinogram interpolation method based on the average pixel value. The change patterns are tracked by iteratively averaging the values. We use a shepp-logan phantom to evaluate the effectiveness of the comparative interpolation method. The results showed that the streak artifacts were reduced in the proposed interpolation method. In addition, we compared our method with another interpolation method using the peak-signal-to-noise ratio(PSNR) and performance time.
