    Cigale, Boris ; Šinjur, Smiljan ; Zazula, Damjan
    In this paper a prototype of automated quantitative assessment of perifollicular vascularisation is described. Assessment of perifollicular vascularisation is important in the research, perfomed by ... medical team at the Teaching Hospital of Maribor, if the application of hormonal therapy after follicle puncture in natural cycles is really always needed. The proposed algorithm works with 3D power Doppler ultrasound images and consists of several steps. At the first step the position and shape of the dominant follicle is determined. The procedure based on the continuous wavelet transform is utilized. Then vessels contained in 5 mm thick layer around the follicle are categorized according to their diameter. The vessel thickness at certain point is defined as diameter of the largest sphere which includes points and fits entirely inside vessels. The results are statistically evaluated by the histograms of vessel diameters. To improve the visual results the vessel reconstruction, based on minimal spanning trees, is done at the end.
