WebbPixel size can be calculated by dividing the field of view by the matrix size (e.g.FOV 320, Matrix 320x320, Pixel size =320/320=1mm). There are two resolution parameters used in MRI for the production of a two dimensional image i.e. basic resolution and phase resolution. Basic resolution is the number of pixels in the readout direction. WebbThe scan exclusion zone is determined by the MRI scanner's field of view and the size of the patient.
