Abstract
I review the method of Doppler tomography which is widely used to understand the complex emission line profile variations displayed by accreting binary stars. Doppler tomography uses the information encoded in line profiles as a function of orbital phase to calculate the strength of emission as a function of velocity, using a process closely related to medical X-ray tomographic imaging. I review applications which have revealed spiral structures in accretion discs, the accretion flows within magnetically-dominated systems and irradiation induced emission in X-ray binary stars. I also cover some of the more recent extensions to the method which variously allow for Roche geometry, modulation of the fluxes and motion at angles to the orbital plane.
