Session
In this talk, we address the challenges of quantitative MRI (qMRI) reconstruction and introduce COMPAS, a flexible and GPU-accelerated toolkit designed for use in qMRI research. Our evaluation shows that COMPAS significantly reduces reconstruction times, from hours to minutes, using the GPU infracture provided by SURF, including Snellius and LUMI supercomputers.
