B0mapping
B0mapping refers to the process of associating the magnetic field strength of zero (B0) within a Magnetic Resonance Imaging (MRI) scanner. This is a crucial step in ensuring image quality and accuracy. In MRI, the main magnetic field, known as B0, is designed to be as uniform as possible across the entire imaging volume. However, imperfections in the scanner hardware, the presence of the patient within the bore, and even magnetic susceptibility differences in tissues can cause deviations from this ideal uniformity. B0mapping is the technique used to precisely measure and quantify these field variations.
The process typically involves acquiring specialized MRI sequences that are sensitive to local field inhomogeneities. These
The primary applications of B0mapping are for correcting image distortions and signal losses that occur due
