Abrégé
(EN)
Multi-dimensional wavelet tomography is performed by iteratively projecting a multi-dimensional image (100) across a range of orientations so as to produce a plurality of one-dimensional projections which collectively form a projection image thereof (202, 204); and then performing wavelet decomposition upon the projection image thereof so as to form a pluratlity of projection subimages each containing particular boundary and angular characteristics of the original image (208, 210, 212, 214). Such wavelet decomposition facilitates segmentation and reconstruction of selected characteristics of the original image.
