Abstract
In this paper I review the method of Doppler tomography proposed by T. Marsh and K. Horne for indirect mapping of gaseous flows in the cataclysmic variable stars. These stars are compact binaries with mass transfer between the components. Theoretical studies predict various gaseous structures in the systems as streams, accretion disks, shock waves, etc. Unfortunately, the cataclysmic variables are rather compact and distant, which make them unavailable for direct imaging. This is where Doppler tomography comes into play helping us see the mentioned structures and compare our observations with theoretical predictions in a more friendly and illustrative manner than, say, analyzing original spectra or light curves.
