The Radon Transform: Basic Principle
<p>Under what real-world circumstances can we easily acquire projections without having easy access to the full volume? Surprisingly often! Let’s consider the case of brain imaging.</p>
<p>If we want to acquire a 3D volumetric image of a brain, we can relatively easily get integrated 2D slices. Think of an x-ray! We can pass energy through the volume and see how much of that energy makes it through. Each of these 2D x-ray images represents line integrals through the 3D volume. We can acquire lots of x-ray images at different geometries about the skull, e.g., from the left side, from the front, from the right side, and all the angles in between.</p>
