  • We consider the inverse problem of estimating the spatially varying pulse wave velocity in blood vessels in the brain from dynamic MRI data, as it appears in the recently proposed imaging technique of Magnetic Resonance Advection Imaging (MRAI). The problem is formulated as a linear operator equation with a noisy operator and solved using a conjugate gradient-type approach. Numerical examples on experimental data show the usefulness and advantages of the developed algorithm in comparison to… CONTINUE READING
