Improved inspection reliability, cost reductions and environmental concerns are today's main factors driving the selection of radiographic techniques. Thanks to the progression of silicon technologies and the current level of electronics, signal processing and transfer are becoming efficient and affordable for use in the NDT industry.
Flat panels are a combination of electronic and silicon technologies that provide direct conversion for X-ray image processing, instead of using film. Flat panels are a range of 2-dimensional detectors that significantly reduce exposure time, giving a wider range of thicknesses to penetrate with the same energy use.
Flexibility
Compared with silver radiography (film), the panels provide :
- choice of beam incidence on a user-selected view,
- enlargement capabilities,
- and reduced inspection costs.

The resolution
Flat panel resolution depends on a number of factors. Pixel size will determine the spatial resolution of the detector, and should be selected taking into account budget, applications and X-ray sources. The smaller the pixelt, the higher the resolution. But the same result can sometimes be achieved using magnification if the exposure geometry and X-ray sources are correctly selected.
Pixel size directly interferes with the modulation transfer frequency (MTF). The MTF defines the sharpness of the system to display the finest details. This is then the final result in terms of definition for said detector. MTF are expressed in line pairs. The panel's electronics is another very important factor, as it will gather and send the signal to the computer with varying degrees of efficiency depending on construction and quality. For example, shielding will ensure that no noise or damage occurs within the module.
"Real" Real time
A fast conversion system where no latency is expected thanks to the operating mode. Acquisition rates are as fast as a human eye can see, and there is no integration time. However, if required, the user can freely choose the integration parameters and obtain a slower frame rate but increase X-ray sensitivity.
Image processing
If you display a given size on a defined area, and then increase the size of the area displayed, you'll have increased definition and precision when measuring the indication. This will help highlight tiny details that are barely visible. It will help you with interpretation and provide an excellent tool for real-time monitoring.
We offer a wide choice of both static and dynamic flat panels to meet your needs.
