Volumetric imaging of a phantom. (a) Photoacoustic image of the phantom without the UV metasurface in which the visualizations are displayed in the maximum-amplitude-projection (MAP) view, (b) B-scan image, and (c) three-dimensional view. (d) Photoacoustic image of the phantom using the UV metasurface in which the visualizations are displayed in the MAP view, (e) B-scan image, and (f) three-dimensional view. The white dotted lines in (a) and (c) indicate the positions of the B-scan images in (b) and (d), respectively.
