How does the sinogram of Figure 4 reveal the density map on the BGA plane? The Radon Transform The operation of creating a linear profile by integrating a 2D density map over parallel rays at a given angle is a Radon Transform. Figure 5: The value of the Radon transform in (ρ, θ) is the integral of
