This paper discusses interactive 3D reconstruction of ultrasonography model. The proposed scheme can be divided into three modules, consisting of Image Segmentation, 3D Model Reconstruction and Interactive Model Editing.More specifically, a set of 2D radial scans acquired from ultrasonography were segmented using Active Contour, resulting in an unorganized set of 3D points delineating an object of interest on multi-planar images. These points were subsequently fitted with a 3D surface model by an expansion of Spherical Harmonics. As accurately segmenting ultrasound images with low SNR can be challenging, this fitted model will be later interactively adjusted to be more properly coincided with underlying structure subject to expert’s opinion. The contribution of this paper is therefore the algorithm and the organizing of related data structure which lend to responsive rendition of the parametric surface being edited.
