Abstract
A method for manufacturing a stimulable luminescent storage screen, of the type used to store a latent x-ray image, with the image being read-out by excitation of the screen with radiation of a first wavelength, thereby causing the screen to emit radiation of a second wavelength, includes the step of using a transparent single crystal as the initial material for making the screen, and working the transparent single crystal to form the screen. Working of the transparent single crystal can be in the form of pressing the crystal, heating the crystal, or both.
