Abstract (English):
The paper presents a new tool for constructing Doppler tomograms: Tomo-V (https://tomo-v.inasan.ru), developed on the basis of the Algebraic Reconstruction Technique (ART). Previously, the ART method was not widely used in tomography since its direct implementation had high computational complexity. The author developed a fast version of this algorithm, which made it possible to implement it as a web application that runs at an acceptable speed in a browser on a personal computer. Using this method, it is possible to obtain sharp tomographic images from blurred profiles; in addition, the method has shown good results in restoring images from noisy data, from a small number of profiles, and from profiles contaminated with absorption lines and the emission of an expanding envelope. Tomo-V also includes tools for analysing the obtained tomograms, allowing one to display accretion disks and Roche lobes on the tomogram as well as the back projection of the tomographic image onto the flow elements in spatial coordinates.
