Principles of CT and CT Technology
WebConclusion: Faster CT gantry rotation reduces scan time and motion artifacts. However, accelerating rotation time increases image noise and streak artifacts. Therefore, a slower CT gantry rotation speed is still recommended for higher image quality in some cases. WebUsing a slower gantry rotation speed (during which the bubble would travel farther), there is an even more pronounced reconstructed arc pattern (Figs. 5C and 5D ). At a 90° gantry offset, a different, but still inconsistent, sinogram is acquired, leading to a difference in the shape of the artifact ( Fig. 5E ).
