electrostatic imaging

electrostatic imaging
a method of visualizing deep structures of the body, in which an electron beam, rather than x-rays, is passed through the patient and the emerging beam (unabsorbed electrons) strikes an electrostatically charged vacuum-packed plate, dissipating the charge according to the strength of the beam. A record (e.g., a film) is then made from the plate.
