Abstract

We discriminated various concentrations’ contrast mediums by spectral photon-counting CT imaging. Contrast media increase the contrast of tissues in x-ray computed tomography (CT) imaging. Conventional x-ray CT uses contrast agent liquids including high x-ray absorption materials like iodine. Spectral photon-counting computed tomography (SPCCT) imaging has the capability of discriminate each contrast mediums with low concentration in one scan by their K-edge if its energy is located in the detectable energy range. The purpose of our research is to reveal the discriminability of contrast mediums by K-edge imaging under the various conditions of concentration included in a water included acrylic phantom with low x-ray exposure.
