Y.HDR-Inspect – X-ray inspection using digital “highly dynamic radioscopy”
Over the past 2 years, highly dynamic radioscopy (HDR) from YXLON has revolutionized inspection via X-rays. Details in thin and thick regions of the inspection item become visible while the item is in motion and without constant adjustment of the X-ray parameters.
The term “highly dynamic radioscopy” means that a high level of detector dynamics exists in relation to depth resolution on the one hand, and that a high level of dynamics is present in relation to the image refresh rate on the other. Radioscopy, or inspection in motion, makes sense only when the image refresh rate is high.
The prerequisite for HDR is a low-noise, fast detector displaying a high level of dynamics in combination with software optimally calibrated to the detector and fast filter algorithms.
The structural noise that occurs even at high doses caused by pixels’ different gray-scale levels when receiving an identical dose can be prevented through multi-gain calibration and a correction of non-linear detector pixels.
Both the complex pixel correction and the algorithms similar to a band-pass filter require very efficient conversion within the software code to be able to be used jerk-free at 30 images per second.
The filtering effect can be optimally adapted in fine steps to the material to be inspected and to wall strengths.
This technology is available in the YXLON X-ray systems Y.MU2000-D and Y.Multiplex.
