 Product Information


 High Resolution

 High Conversion Factor

 High Contrast Ratio

 This X-ray Image Intensifier is intended to be connected with IEC Class I equipment.

 This Image Intensifier replacement has been perfected by the integration of several aspects

 of advanced technology

 The input window is of a thin metal plate, which has good X-ray transparency

 characteristics and reduces X-ray scatter.

 It uses a thick input phosphor screen made with an extremely fine pillar shaped

 structure. This has high X-ray absorption and very high convers ion efficiency.

 In addition, there is a thin output phosphor screen on a single thick-glass output

 window with an anti-reflective coating, offering very high contrast for small details,

 very low structure noise and high MTF characteristics. 

 This replacement, employing these manufacturing techniques provides outstanding

 performance in resolution, brightness, contrast and noise.

 The Image Intensifier is supplied in the Siemens 40cm housing, which provides mu-metal  magnetic shielding. The housing is lined with radiation shielding designed to comply with FDA Radiation Performance Standards, 21 CFR subchapters J
