he new CR 50P portable computed radiography scanner from GE Inspection Technologies is light and compact enough to allow the benefits of computed radiography to be realised at remote locations in applications requiring both high throughput and high resolution. With a laser spot size of just 50 micron and with the high resolution afforded by today’s IPS display screens, the new scanner will allow computed radiography to assume more and more of the duties which have conventionally been restricted to film radiography.
Weighing just 22 kilograms, the CR 50P offers excellent image quality through its optimised optics and a scan resolution which can be user-variable from 50 to 130 ï¿½m pixel pitch. Scan results can be displayed on a connected laptop or a local high resolution monitor. The output data can also be processed using Rhythm software, which has been specifically designed for NDT applications and offers advanced image review tools and data management and storage. In addition, Rhythm features extensive data sharing capabilities, allowing significant improvements in productivity and faster identification of defect indications.
The CR 50P accepts flexible, phosphor imaging plates up to 35.5cm (14 inches) wide and of virtually any length. Plates can be processed on a continuous basis, with one plate being fed into the unit while another plate is being scanned. The plates have been designed to operate in harsh environments and feature a special protective, scratch-resistant layer. They are available in a sensitivity range from D7 – D4 depending whether resolution or speed is the governing inspection factor.
With its intrinsic flexibility, portability and efficiency, the CR 50P will find application throughout the industrial and process spectrum but especially in the oil and gas and aerospace sectors.
Ultimately, Computed Radiography was chosen for its fast exposure and scanning times to easily meet the cycle constraints. The only problem was that the technique did not carry DNV approval for this kind of work. Consequently, GTSG arranged for inspectors from DNV, a global risk management and certification agency, to fly out to the site, to carry out the required approval procedures. As a result, the technique was approved to DNV OS-F101 and it has proved possible to achieve better than 1.2% sensitivity at 100Âµm resolution, a quality equal to that achievable by film radiography.
In operation, GE Sensing & Inspection TechnologiesÂ’ IPS and IPC2 phosphor imaging plates were placed around the weld on top of an insulating layer to protect them from the very high pipe surface temperatures. They were then exposed to the radiation of a source carried by an X-ray crawler inside the pipe. Exposure times were very short, a particular feature of these latest imaging plates, which also offer a wide dynamic range and exposure latitude, minimizing the need for time-consuming retakes. The exposed plates were fed into an adjacent CR50P portable CR scanner.
GEÂ’s CR50P weighs just 22 kg (48.5 lb) and offers excellent image quality through its optimized optics and a scan resolution which can be user variable from 50 to 130Âµm pixel pitch. Plates can be fed on a continuous basis, with one plate being fed into the unit while another plate is being scanned. Results are displayed on a black and white monitor with a resolution of 3 million pixels and 65000 grey scale. The data is managed and processed using GEÂ’s Rhythm software platform, which offers advanced image review tools and storage cabalilty. Data is stored in the DICONDE protocol, which has been specifically developed for non-destructive testing inspection applications and allows images to be stored with text to facilitate future database searches. Currently, GTSG is storing data on CDs and DVDs, although this can be converted to computer hard drive if required. Moreover, the Rhythm suite also includes Rhythm Archive, an elegant and comprehensive long-term data storage solution.
Since obtaining the DNV approval, the technique has also been approved to AS 2885.2 and as Dave Ryan, managing director at GTSG, says, Â“We believe that Computed Radiography has a lot to offer the oil and gas industry and we are very pleased to have played a part in ensuring that the technique has gained the approvals it merits. We view it as an important addition to our existing range of NDT technologies.Â”

Rhythm Local Archive
â€¢ The Local Archive module allows archiving of component,
study and report data on a single removable media from
any removable device that has a WindowsÂ®-based driver. It
is useful for organizations that have â€œshelf managedâ€�
archives or that want to distribute images via removable

Quality Control Module
â€¢ The Quality Control module is a quality assurance tool for
post-processing acquired data. It verifies that images and
studies are correct and that they have the right information
associated with them before they are shared or permanently
stored and provides the capability to modify them.
â€¢ The module assesses if component or technique data was
entered incorrectly, if images are not in the right order, that
DICONDE information is incorrect or missing, or if window
level settings during acquisition were not optimal.
â€¢ The Quality Control module also provides access to the study
status history so that you can determine when components
were inspected, by whom, and with what outcome.
Rhythm DlCOM Print Module
â€¢ The DlCOM Print module provides a solution for the inevitable
need to provide print images from within the digital imaging
network. It supports printers from high-end DICOMcompliant
ones to off-the-shelf printers with standard
WindowsÂ® drivers. It supports color and monochrome
printers and also allows for multiple printer connections.
â€¢ It allows the printing of series or studies in pre-defined film
layouts or from your custom layouts. In addition, it offers
a â€œvirtual film sheetâ€� that allows you to compose print jobs
on the fly from within the Viewing sectionâ€”rearranging,
annotating and post-processing images before sending
them to the printer.
Enhance Rhythm Functionality with Optional Modules
The Right Tools for the Job
One of the major factors that allows Rhythm to increase
inspection efficiency is its integral range of advanced,
Rhythmâ€™s advanced image review and tools enable the
â€¢ Save time through quicker image evaluation.
â€¢ Improve quality of inspections through advanced review tools.
Wall Thickness Measurement
â€¢ Performs computer-assisted wall thickness measurement to
detect local corrosion in projection radiographs by use of
tangential or penetration wall measurement tools.
â€¢ Saves the measurement results and the exposure parameters.
Area Measurement and
â€¢ Allows users to select an area around a porosity and
automatically calculate the loss of material/area
measurement of the defect.
Multi-film Inspection Tool
â€¢ Reproduces the conventional film method of putting two or
three different sensitivity films on top of one another and
shooting a part, then having different cross-sectional
thickness ranges available for analysis.
This tool splits the dynamic range of the selected
radiographic image into two or three exclusive partitions for
better visualization and analysis of image features.
Defect and Material Loss
â€¢ Allows users to measure material loss in the X-ray beam
direction (similar to the wall thickness penetration
measurement), showing material loss instead.
Protecting Your Future
Rhythm doesnâ€™t just ensure your NDT needs are met today,
but also looks to what you may require in the future.
This is achieved through the scalable architecture intrinsic to
the design of the software, DICOM/DICONDE compliance, and
GE Inspection Technologiesâ€™ focus on application-specific tools.
â€¢ While Rhythm is currently configured for X-ray inspection
management, ultrasonic and eddy current capabilities are
planned for the near future.
â€¢ As your requirements grow, you can add more review
stations, database capacity and DVD jukeboxes to your
system. This ensures you will always have the capacity
required without the expense of investing in a new solution.
â€¢ Because the software is DICOM/DICONDE compliant, you
will not face the problems of being locked into propriety
solutions where time and expense is wasted on maintaining
previous NDT systems.
â€¢ GE Inspection Technologies is committed to working closely
with you to develop application-specific tools that can be
deployed quickly as Rhythm plug-ins.
