Photoacoustic image reconstruction from a frequency-invariant source localization perspective

Salehin, S.M.Akramus; Abhayapala, Thushara


Photoacoustic imaging provides high spatial resolution images of biological tissues and is useful for molecular imaging. The exact reconstruction algorithms for photoacoustic imaging are either slow or assume a continuous sensor with infinite bandwidth. We propose a novel reconstruction method which expands the source distribution function in the Fourier-Bessel domain. The source distribution can be reconstructed from frequency samples corresponding to the Bessel zeros. Sparsity of the source...[Show more]
