Comparative study of one-step and two-step quantitative fluorescence photoacoustic tomography

PK Pandey, O Gottam, N Naik, A Pradhan - Applied Optics, 2019 - opg.optica.org
Fluorescence optical tomography (FOT) is a well-known imaging technique, where
fluorescent biological markers are injected to tag targeted tissues (tumors, proteins), and the …

Gradient-based one-step fluorescence photoacoustic tomography

PK Pandey, O Gottam, N Naik, A Pradhan - Applied Optics, 2020 - opg.optica.org
We propose a gradient-based scheme to solve the fluorescence photoacoustic tomographic
(FPAT) problem in a fully nonlinear one-step setting, which aims to reconstruct the map of …

One-step fluorescence photoacoustic tomography with the optical radiative transfer model

PK Pandey, J Bharadwaj, N Naik, HO Aggrawal - JOSA A, 2020 - opg.optica.org
We present adjoint-based Jacobian as well as gradient evaluations and corresponding
reconstruction schemes to solve the fully nonlinear, optical radiative transfer modeled one …
