The paper deals with an imaging computer tomography method based on simple image processing techniques for two phase flow analysis. Moreover, it has been presented the algorithm of 3D bubble trajectory reconstruction using a single high speed camera and system mirrors. In experiment glass tank filled distilled water was used. nozzle through which bubbles were generated placed in center bottom. Through use basic analysis such as noise reduction, smoothing, edge detection few algorithms like close contour filling, tracking etc. proposed became possible to draw out trajectories gas paths liquid. measurement error estimated. maximum recorded this within limits ±0,65 [mm] certain set parameters like: resolution, mirror angle deviation z axis from 90o vertical line. Trajectories subsequently departing visualized form figures.
