Note that if P ⊂ H∞ , then the P -polygon Q is also a U -polygon for the set U of unit vectors associated with points in P . Let F be a class of finite sets in Rn and P a finite set of points in Rn . We say that F ∈ F is determined by the discrete point X-rays at the points in P if whenever F ∈ F and Xp F = Xp F for all p ∈ P , we have F = F . 3 Discrete Point X-Rays at Two Points Theorem 1. Let p1 and p2 be distinct points in Z2 . Then there are different convex lattice sets that meet L[p1 , p2 ] and have equal discrete point X-rays at p1 and p2 .

Pm , m (ii) i=1 |Xpi F1 −Xpi F2 | = 2(m−1), and (iii) |F1 ∩φ(F2 )| ≤ 3 (or ≤ 4) for any affine transformation φ : R2 → R2 (or projective transformation φ : P2 → P2 , respectively). Thus there is an even worse instability for discrete point X-rays than for discrete parallel X-rays, for which the results are the same except that in (iii) the bounds depend on m. She also extends these results to higher dimensions. According to a couple of experts in electron microscopy (private communications), there might be a chance to realize discrete point X-rays experimentally for small samples.
