High resolution anti-scatter x-ray grid and laser fabrication method |
摘要 |
<p>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 (320) between the substrate (114) and a high power laser (310); 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. <IMAGE></p> |
