Abstract

The radiative transfer equation and the broken ray Radon transform are mathematical models for photon transport. The broken ray transform may arise from an approximation of the radiative transfer equation in low scattering regime. Like the X-ray (Radon) transform, these two areas are rich sources of inverse problems and the foundation of several important imaging methods. The radiative transfer equation has been intensively studied in optical tomography and, more recently, quantitative photoacoustic tomography. The broken ray transform arises in single-scattering optical tomography, emission tomography using Compton cameras, and Compton scattering tomography. It also appears in partial data Calderon problem. Several inverse problems arise in these topics and their solutions are both related and diverse.
This mini-symposium will gather several interesting talks across all aforementioned applications. We hope that it will provide a panoramic view in the related topics and inspires more discoveries on their connections.
