TABLE I.
Field of View (FOV) and No. Of Pinholes (Nx, Nz) for Different Flat Detector Sizes (Thus Acceptance Angles) for a = 120 mm. To Calculate the no. Of Pinholes, it is Assumed That the Pinholes are All Placed on a Sphere of Radius 200 mm (i.e., All Pinholes Point to a Co-Center 200 mm Below Their Axis)
