Abstract

This paper introduces the general principles involved in inverse problems in medical imaging, and describes the main theoretical principles behind Time-resolved Optical Absorption and Scattering Tomography (TOAST). The problem is viewed as the optimisation of an error-norm derived from correlated statistics of the time-dependent photon intensity at the surface of an object. The field is compared with Electrical Impedance Tomography (EIT). A comparison of inverse methods are made and several regularisation schemes are described.
