  • Title: New methods of imaging in diagnostic radiology.
    Author: Johns HE, Fenster A, Plewes D.
    Journal: Radiology; 1975 Aug; 116(02):415-21. PubMed ID: 1153747.
    Abstract:
    The basic ideas of electrostatic imaging with special reference to ionography are reviewed. The concept of edge contrast is explained in terms of calculated powder particle trajectories and methods for controlling edge contrast are presented. Also, methods for reading a foil from outside the ionography chamber using the electric field extending through the foil are described. An example of an image taken with liquid in the chamber (liquid lonography) is presented, and the possible extension of liquid ionography to nuclear medicine is discussed.
