ABSTRACT

In order to make the link between the 2D and 3D image representation, we use a discrete geometry tool named the Mojette transform. This is an exact numerical projector giving a 2D projection from a 3D volume. The fact that this operator is fast, exact and linear allows for coping with correlations in the two domains. This tool is recalled in section 2. A modified version called the Line Mojette transform is also explained since developped for the 3D bone architecture analysis. In section 3, we recall our first experiments since 2010 and their results.
