Frequency domain, photoacoustic tomography with sparse frequency samples

Salehin, S.M.Akramus; Abhayapala, Thushara


Photoacoustic imaging provides a high resolution imaging solution for biological tissues. In this paper, we consider recovering the z-averaged spatial distribution using a cylindrical array of sensors long in the z-direction. This configuration can be applied for breast imaging. In previous frequency domain algorithms there is no way to determine the optimum, minimum number of frequency samples required. We propose a novel frequency domain algorithm which uses a minimum number of frequency...[Show more]
