(A) Images generated from an SPCCT phantom scan of AuNP of 4 nm ranging from 0 to 10 mg Au/mL in concentration. Conventional CT equivalent image, water image and gold image (left to right). (B) Attenuation rate values for the AuNP formulation for the SPCCT scanner at 120 kV. No significant difference of attenuation rate was found between any AuNP formulation. (C) Ratios of measured gold concentrations from gold specific images and actual gold concentrations. No significant difference in ratio was found between any AuNP formulation. (D) Measured gold concentrations from gold specific images are in agreement with the actual gold concentrations.
