Removing background phase variations in susceptibility‐weighted imaging using a fast, forward‐field calculation
Abstract
PURPOSE: To estimate magnetic field variations induced from air-tissue interface geometry and remove their effects from susceptibility-weighted imaging (SWI) data.
MATERIALS AND METHODS: A Fourier transform-based field estimation method is used to calculate the field deviation arising from air-tissue interface geometry. This is accomplished by manually drawing or automatically detecting the sinuses, the mastoid cavity, and the head geometry. …
