Resolution and contrast improvement of photoacoustic tomography with two-dimensional frequency domain delay multiply and sum signal reconstruction method

Abstract

Photoacoustic tomography (PAT) provides bio-imaging with high optical absorption contrast, high acoustic resolution, and deep penetration. Previously, we proposed a frequency domain delay-multiply-and-sum (F-DMAS) signal reconstruction method to axial resolution of optical resolution photoacoustic microscopy. Here we extend the F-DMAS to 2D F-DMAS (2D F-DMAS) and apply 2D F-DMAS to PAT images to improve spatial resolution and contrast simultaneously. Simulations of PAT are used to verify the efficacy of the proposed 2D F-DMAS. The improvement achieved with the proposed method will be further verified by phantom experiments and in vivo imaging.
