Discrete Point X-rays
Paolo Dulio, Richard J. Gardner, Carla Peri · SIAM Journal on Discrete Mathematics · 2006
A discrete point X-ray of a finite subset FM of Rn at a point p gives the number of points in F lying on each line passing through p. A systematic study of discrete point X-rays is initiated, with an emphasis on uniqueness results and subsets of the integer lattice.
