Figure 3: (a) SKBR3 cell line phantom. SKBR3 cells with Herceptin-AuNPs show more volume, indicating more gold is present. Material decomposition basis images show Au (yellow/orange, the hue represents the concentration), lipids (pink), and water-like material (grey). (b) Raji cell line phantom; Raji cells with rituximab-AuNPs show more volume and brighter hue, indicating a high concentration of gold present.
