Abstract
Spectral shaping (also known as spectral filtration) has been utilized in some of the latest computed tomography (CT) systems. This technique involves using tin (Sn) or silver (Ag) filters, which selectively absorb low-energy photons. This review aims to demonstrate the utility of spectral shaping across a wide range of protocols and clinical situations. Spectral-shaped CT protocols using tin filters allow for the acquisition of diagnostic images and greatly reduce the radiation dose, metal artifacts, and photon starvation. These features make spectral shaping suitable for various clinical situations in diagnostic and interventional CT imaging.
