Abstract

A method of a virtual X-ray colonoscopy includes scanning (204) a dark-field contrast (144) insufflated colon lumen (140) with an X-ray scanner (110) configured for dark-field-contrast, which generates dark-field-contrasted projection data and attenuation projection data. The dark-field-contrasted projection data and the attenuation projection data are reconstructed (206) into one or more dark-field-contrasted images (148).
