Web2 important criteria = field uniformity (homogeneity) and field strength. How strong, in units, are the magnetic fields in the MRI scanners typically used for fMRI? Range for humans to 1.5 to 11 T (usually 1.5, 3, or 7 T) What are the differences between volume coils, surface coils, and phased array coils? WebSSFP-based fMRI techniques, known for their high specificity and low geometrical distortion, look promising for high-resolution brain mapping. Nevertheless, they suffer from lack of speed and sensitivity, leading them to be exploited mostly in high-field scanners.
