NVIDIA GPU grant for multi-energy image reconstruction research


The multi-energy X-ray imaging group led by Professor Miika T. Nieminen has received a NVIDIA Quadro P6000 GPU from the NVIDIA GPU grant program for image reconstruction algorithm research. The powerful architecture and superior memory of 24GB of the received GPU is ideal for heavy computations involved in the research.
