New digital
x-ray imaging
capabilities
GE Sensing & Inspection Technologies
has launched the new DXR 250RT
detector, which combines with the
proven Vistaplus V imaging software
to allow on-line, enhanceable, x-ray
imaging of spiral and longitudinal SAW
welds.
The DXR 250RT, which was originally
developed by GE for the highly
demanding medical sector, offers
contrast resolution of less than 1%, and
a spatial resolution of 200 micron.
As a result, it is suitable for resolving
very small indications in high wall
thicknesses. It has a total active area
of 205x205mm, and is suitable for
operation in temperatures ranging from
10 to 35°C.
Image processing and enhancement
of detected images is provided by
the Vistaplus system, a PC-based,
Windows XP Pro-driven system, which
is ideally suited for rapid evaluation
and assessment of x-ray images. It is
of modular design, so that it can be
adapted to suit most user requirements,
and its user interface is optimised for
fast macro development to suit specific
automation needs.
In operation, a real-time image of the
pipe weld being inspected is displayed
on the control desk monitor, while
simultaneously an image that can be
enhanced is also shown. Enhancement
can be carried out using functions
such as contrast adjustment, zoom
and digital filter to allow calculation of
defect area and reference comparison
to facilitate sentencing. Digital images
can be stored in various conventional
formats and, in cases where extensive
archiving is required, GE’s Rhythm
archiving solution can be applied.
GE Sensing & Inspection’s products
are used in a wide range of industries,
including oil and gas, power gener-
ation, aerospace, transportation and
healthcare.
