> Finally, in possibly his most ingenious invention, Hounsfield created an algorithm to reconstruct an image of the brain based on all these layers. By working backward and using one of the era’s fastest new computers, he could calculate the value for each little box of each brain layer. Eureka!

And, of course, they glossed over the most interesting part by simply saying "an algorithm." I know that modern CT scans use Marching Cubes [1], which is what that particular algorithm was developed for, but that came later in the 80s.
