Abstract:Objective: Imaging of superparamagnetic iron oxide nanoparticles based on their non-linear response to alternating magnetic fields shows promise for imaging cells and vasculature in healthy and diseased tissue. Such imaging can be achieved through x-space reconstruction typically along a unidirectional Cartesian trajectory, which rapidly convolutes the particle distribution with a “anisotropic blurring” point spread function (PSF), leading to images with anisotropic resolution. Approach: Here we propose combin… Show more
