T
hales’new QX series of X-Ray Image Intensifiers
(XRII), not only retain all the features on its proven
HX generation, but also offer higher contrast,
resolution, conversion factor and DQE.
TH 9447 QX
The TH 9447 QX is a 16-inch, quadruple-field
XRII with a 35 mm output window, and provides
the ultra-high contrast needed for high-end
digital radiology applications. When coupled
with a high-performance 1k x 1k CCD camera,
it offers a remarkably high level of image quality:
The 35-mm output image diameter ensures very
high resolution.
The housing dimensions are no larger than the
14” tubes currently used and the tube is fully
interchangeable with existing 14” models.
Its reduces length makes it easier to fit the tube in
the X-ray table. The TH 9447 QX is fully compatible optically, electrically and mechanically - with
the TH 9447 HX.
• advanced input screen, for high DQE,
high resolution and lower X-ray exposure,
Various housings, mountings and a magnetic-field
correction module (ADCS) integrated inside
the housing are available on option.
• ultra compact output phosphor screen,
for unrivaled resolution, low structural noise,
and a high conversion factor,
The power supplies are microprocessor-controlled
and comply with the EMC standards. They also
feature blanking capability on request.
• thick output window, for high contrast and
compatibility with digital image processing.
This product is designed, developed and
manufactured at an ISO 9001 and EN 46001
registered production site.
