GPIG - Département Images et Signal (DIS) - Equipe GPIG - Groupe Adéquation Algorithme ArchitectureThe medical imaging improvements in spatial and temporal resolutions involve increasing needs in computational power. The software, algorithmic and hardware accelerations are called to reduce the current technologic gap existing between acquisition and reconstruction systems.In this context, a hardware architecture of 3D backprojection for Positron Emission Tomography (PET) is proposed. Thanks to an Algorithm Architecture Adequacy, our architecture overcomes successfully the limitations due to the latency of the external memory SDRAM like. It has been implemented on a SoPC (System on Programmable Chip) and its performances have been compared t...
