[The preliminary quantitative analysis of the structures of neovascular morphology of tumours at different stages based on synchrotron radiation].

Microvessel networks were imaged by means of synchrotron radiation CT, A sliced loading and double threshold method was utilized for extracting vessels from large quantities of data (2 GB-5 GB). Preliminary analysis on the development of tumor microvessel networks was performed by statistically analyzing volume rendering and two qualitative factors, micro vessel density (MVD) and fractal dimension(FD).
