We previously introduced a new high resolution diffuse optical imaging modality
termed, photo-magnetic imaging (PMI). PMI irradiates the object under
investigation with near-infrared light and monitors the variations of temperature
using magnetic resonance thermometry (MRT). In this paper, we present a real-time
PMI image reconstruction algorithm that uses analytic methods to solve the
forward problem and assemble the Jacobian matrix much faster. The new algorithm
is validated using real MRT measured temperature maps. In fact, it accelerates
the reconstruction process by more than 250 times compared to a single iteration
of the FEM-based algorithm, which opens the possibility for the real-time PMI.
