Siemens 40cm Replacement
Quadruple Input Field:
(16 /12 /9 / 6) Inch
Output Image Diameter: 32mm
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
