Illustration of the experimental setup and procedure. a Photo of the photon counting CT configuration used to take 2D projections (256 × 1280 pixels) of the phantom; b the 200th row in the projection is selected as the line of interest (LOI) and used to obtain the difference between the projection profiles of the phantom when it is filled and when it is empty. The projections have been contrast enhanced for better viewing and the vertical white lines corresponding to gaps between detector chips are removed during processing; c The difference in area between the projection profiles of the empty and filled phantom are used to determine the LAC of the liquid material
