Roughly speaking the support of a function is the set of points where the function does not vanish. To get a useful concept we need to add points that are very near to points where the function is non-zero. As the definition is the same in all dimensions we give it for functions defined on Ê n . 1. Let f (x) be a function defined on Ê n . A point x belong to the support of f if there is a sequence of points < xn > such that (1). f (xn ) = 0, (2). limn→∞ xn = x. This set is denoted by supp(f ). CHAPTER 2.

Beer’s law state that di d(log i) = −m(s)i(s) or = −m(s). ds ds Integrating this equation from s = a to s = b gives b i(b) log =− i(a) m(s)ds. 4. We consider a two dimensional example. 2(a). The X-ray source is isotropic which means the outgoing flux is the same in all directions. CHAPTER 2. A BASIC MODEL FOR TOMOGRAPHY 38 r o S source (x,y) (a) A point source of X-rays (b) The flux through a curve not enclosing the source is zero. 2: Analysis of an isotropic point source. Because the source is isotropic, the intensity of the beam is only a function of the distance to the source.

Let e(θ) ≡ 0 be a function that satisfies e(θ) + e(θ + π) = 0. 2 we know that if hD has two derivatives such that hD + hD > 0 then hD (θ) is the shadow function of a strictly convex region. 3. LINEARITY 21 as well, then hD + e is also the shadow function for a different strictly convex region. Observe that hD (θ) + e(θ) is the shadow function for a different region, D which has the same width of shadow for each direction as D. That is wD (θ) = (hD (θ) + e(θ)) + (hD (θ + π) + e(θ + π)) = wD (θ).
