"NettetField of View (FoV): total area that can be viewed by the lens and imaged onto the camera sensor. Working distance (WD): object to lens distance where the image is at its sharpest focus. Depth of Field (DoF): maximum range where the object appears to be in acceptable focus. Sensor size : size of the camera sensor’s active area. " - How the field of view affects an image

NettetPixel 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.

NettetAccording to MicroscopyU, there are wide field of view microscopes in production that offer larger viewing images, but these need microscopes corrected to take advantage of this extra space properly.
