First 3D Photoacoustic Images With a Prototype Tabletop Instrument

First 3D photoacoustic images were acquired with a prototype tabletop instrument. A 3D resolution phantom included two intersecting light absorbing polyethylene fibers (150 µm in diameter each). Scan duration – 36 seconds. Reconstructed volume – 10mm x 10mm x 20mm. Voxel size – 50 µm.
