Abstract

Photoacoustic imaging (PAI) has several advantages in achieving high-contrast imaging of blood vessels or tumors over conventional ultrasound imaging. However, most PAI systems use conventional linear array transducers and need complex algorithms to reconstruct photoacoustic (PA) tomography or three-dimensional images. In this research, we successfully demonstrated the use of a 4F acoustic lens to realize 3D PAI system. The 3D PAI system has achieved lateral resolution of 0.5mm, depth of field 2.5mm.
