  • System for fabricating anti-scatter x-ray grid
    Patent number: 6733266
    Abstract: A method for fabricating a substantially transparent polymer substrate for an anti-scatter x-ray grid for medical diagnostic radiography includes positioning a phase mask between the substrate and a high power laser; providing a laser beam from the laser; conditioning the laser beam; ablating a first portion the substrate through the phase mask with the conditioned laser beam; and moving the substrate; and ablating a second portion of the substrate through the phase mask with the conditioned laser beam.
    Type: Grant
    Filed: August 15, 2000
    Date of Patent: May 11, 2004
    Assignee: General Electric Company
    Inventors: Renato Guida, James Wilson Rose, Kenneth Paul Zarnoch, Gary John Thumann
