Ｘ線検出器
Document Type and Number:
Japanese Patent JPH11500857
Kind Code:
A
Abstract:
An X-ray image intensifier tube (1) includes an entrance section (2) for converting high-energy X-rays of from 100 keV to 120 keV into an electron beam (10). The entrance section (2) had a conversion layer (3) with a filter layer (5) for absorbing a part of comparatively low energy (from 60 keV to 80 keV) of the X-rays and a conversion layer for converting the high-energy X-rays of approximately from 100 keV to 120 keV into radiation whereto the photocathode is sensitive.
