Webifanbeamconverts the fan-beam data to parallel beam projections and then uses the filtered back projection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a power of 2 before filtering to WebAlumawood Newport Non-Insulated Ceiling Fan Beam. Fan Beam Dimensions: 1 1/2" x 2 1/2" x 0.048" 6005T5 Aluminum.

WebIn the fan beam projection in matlab, what is the starting point of the projection acquisitions? Is the source considered placed on the right side on the positive x axis and the detectors on the other side or the opposite? Also does the source with detectors rotate clockwise or anticlockwise for 360 degrees?
