Latest Patents
Leroux's latest patents include innovative techniques for image reconstruction based on accelerated methods using polar symmetries. This patent describes an image reconstruction system that utilizes image projection data collected by an imaging system with multiple tubes of response. The method employs a system matrix that maps image projection data to pixels positioned according to a polar or cylindrical coordinate grid. The reconstruction process is optimized through structured matrix-vector computations, which enhance efficiency by storing symmetric data in contiguous memory locations.
Another significant patent by Leroux involves image reconstruction methods based on block circulant system matrices. This iterative method is designed for imaging systems that generate projection data. It includes steps for collecting projection data, choosing a polar or cylindrical image definition, and restructuring the system probability matrix into a block circulant matrix. The method ultimately converts the polar or cylindrical image estimate into a Cartesian image representation, resulting in a reconstructed image.
