Abstract
In the early 1970s Richardson1 and Lucy2 published an iterative method for recovering images of objects that appear blurred. Their method has been rediscovered by Shepp and Vardi3 for imaging radionuclides. The connection between these two seemingly disparate fields of science—restoring optical imagery and radionuclide imaging—occurs because they are inverse-problems having a common mathematical description. The purpose of this paper is to note some implications for restoring optical imagery of recent developments in radionuclide imaging.3-5 These developments yield extensions of the Richardson-Lucy iteration that have proved to be powerful for restoring images from quantum-limited data. An application to images acquired with the Hubble Space Telescope is given.
