We select several CME events and reconstruct the 3D coronal streamer belt configurations for the periods of time before and after the corresponded CMEs. The reconstructions are based on STEREO COR1 observations and made by using a regularized tomography technique (Kramar et al. 2009). For some CME we found noticeable changes in the streamer belt structure. Particularly, for a slow CME on June 1, 2008 (Robbrecht et al. 2009) we found that for a longitudinal range of about 10 degrees in Carrington longitude centered at the CME location, the height of the overlying streamer belt was significantly reduced. This reduction in height persisted for at least 14 days. The reconstruction of the streamer belt before and after the CME allows direct estimate of the mass lost. Also it was found that positions of this and some others CME correspond to regions in the streamer belt where the latter has a double structure (i.e. splitted into two parts).
