What effect does collimation have on spatial resolution? The use of collimation in fluoroscopy does not significantly affect the overall image quality in terms of spatial resolution or scatter when the II input field of view is unchanged.
How does collimation affect spatial resolution? The spatial resolution of the system is a function of collimator response and intrinsic resolution. Because collimator resolution decreases when distance from the source increases, extrinsic resolution also decreases (20). Thus, it is expected that smaller distances provide better results.
What happens when collimation is increased? As collimation increases, the quantity of scatter radiation decreases, and radiographic contrast increases; as collimation decreases, the quantity of scatter radiation increases, and radiographic contrast decreases.
How does collimation affect image quality? Proper collimation is one of the aspects of optimising the radiographic imaging technique. It prevents unnecessary exposure of anatomy outside the area of interest, and it also improves image quality by producing less scatter radiation from these areas.
