WebNov 19, 2024 · The proposed technique takes advantage of the low noise of thicker images and exploits the structural similarity between the thick- and thin-slice images to reduce noise in the thin-slice image. Phantom data and patient cases (n= 3) of head CT were used to assess performance of this method. Images were reconstructed at clinically utilized … WebJun 16, 2024 · Consequently, the use of 3D reconstitution and multiple cross-sectional reconstructions from thin-slice CT data has become widespread. Thus, improving the quality of thin-slice images has become more important . Noise in CT images is mainly caused by the number of X-ray photons and increases inversely with the square root of …
