DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Inverse/79/"
 >Quantitative PAT with simplified PN approximation</a>\nby Yimin Zhong (Du
 ke University) as part of International Zoom Inverse Problems Seminar\, UC
  Irvine\n\n\nAbstract\nThe photoacoustic tomography (PAT) is a hybrid moda
 lity that combines the optics and\nacoustics to obtain high resolution and
  high contrast imaging of heterogeneous media. In this\nwork\, our objecti
 ve is to study the inverse problem in the quantitative step of PAT which a
 ims\nto reconstruct the optical coefficients of the governing radiative tr
 ansport equation from the\nultrasound measurements. In our analysis\, we t
 ake the simplified PN approximation of the\nradiative transport equation a
 s the physical model and then show the uniqueness and stability\nfor this 
 modified inverse problem. Numerical simulations based on synthetic data ar
 e presented\nto validate our analysis.\n
