Abstract

In this paper we examine the imaging performance of an experimental mechanically-flexible antiscatter grid for use with computed radiography. Bucky factors, contrast improvement factors, and signal-to-noise improvement factors were computed from transmittance measurements made with 5-, 10-, 15-, 20-, and 25-cm uniform-thickness water phantoms. These phantoms were selected to span the range of scatter fractions found in chest radiography.
