Multi-Echo Pseudo-Golden Angle Stack of Stars Thermometry with High Spatial and Temporal Resolution Using k-Space Weighted Image Contrast

摘要

A method for producing an image of a subject using a magnetic resonance imaging (MRI) system includes acquiring a series of echo signals by sampling k-space along radial lines that each pass through the center of k-space. Each projection of the radial lines is divided into multiple echoes and successive projections are spaced by a predetermined angular distance. The series of echo signals are reconstructed into a plurality of images, wherein each image corresponds to a distinct echo signal.
