Title:
METHOD AND DEVICE FOR GENERATING X-RAY VIDEO IMAGE
Document Type and Number:
Japanese Patent JP3474217
Kind Code:
B2
Abstract:
PURPOSE: To provide a method, which generates an X-ray video image by a photoconductor which is provided on a conductive substrate and whose surface potential can be read out by a probe, and a device suitable for implementation of this method.
CONSTITUTION: The substrate potential is changed in a test stage after charging of a photoconductor 1 for the purpose of avoiding a video artifactdue to the deviated sensitivity or the frequency dependency distortion of a probe 7. Test data corresponding to the spatial or secondary change of the surface potential of the photoconductor 1 is generated, and correction data which is stored to correct the video data of next X-ray irradiation is formed from this test data.
