The question might seriously be asked: "What do you want to see - penetrameters images or defects?". The four most significant differences are the speed at which an inspection can be accomplished, quality of the image, the equipment used and its related cost and, the method of image analysis and storage. They could not only feed back the real-time location and distribution of the embolic microspheres but also maintained clear X-ray imaging of embolized sites for up to 4 weeks as assessed by digital radiography and computed tomography. sales@jgarantmc.com, Jesse Garant Metrology Center Instead of radiographic film, digital radiography uses a digital image capture device. Double wall penetrameter image quality with image processing is on the order of 2-2T over a wide range of tube diameters and wall thicknesses. Real-time radiography made possible by the NeXray system provides critical advantages over conventional radiography traditionally used for weld inspection: With NeXray’s revolutionary nondestructive testing (NDT) technology, pipeline inspection gets done right. It is interesting to note that the miccrofocus projection technique can also be used with film to produce similarly enhanced radiographic results.

Radiography Procedure Checklist (cont'd) 4. The image is usually rather faint and the method is now only used for thin non-metallic specimens. STANDALONE REAL-TIME DIGITAL RADIOGRAPHY SYSTEM. The digital image processor operates to improve radioscopic image quality in three ways: 1) through the reduction of random noise or "snow" in the radioscopic image, 2) through the improvement of contrast in the radioscopic image and 3) through the improvement of apparent radioscopic resolution by edge sharpening. Damaged insulation is taken as a sign of potential CUI, but this is not always correct. Fluoroscopy, or Real-Time Radiography (RTR), emits radiation into one side of a material and uses sensors on the other side to convert the rays into light, producing a digital image that reveals corrosion, and internal/external defects in real time.

Yet, these successful in-house examination measures must often be followed by approved radiographic procedures before the product can be "sold." The radiographic parameters for real-time radiography are similar to conventional film radiography with special emphasis on . Recent technological developments have closed the gap between the performance levels of radiographic and radioscopic systems. These key points include: 1) equipment qualifications, 2) test object scan plan, 3) radioscopic parameters, 4) image processing parameters, 5) image display parameters, 6) accept-reject criteria, 7) performance evaluation, 8) image archiving requirements and 9) operator qualifications. Performance monitoring is another area where no one device, such as an IQI or penetrameter, will meet every need in a dynamic imaging environment. The optimal geometrical imaging configuration is evaluated and discussed in relation to conventional film radiography. Perhaps the greatest single improvement in radioscopic image quality has come about through the application of digital image processing techniques. Phone: 519-962-5300 The results show that initially, sinks develop in the low solid fraction regions on the surface of . Projection imaging places the scatter-generating test object further away from the test object while the distance from the focal spot to the image receptor remains the same. This battery-operated equipment integrates a Go-Scan CMOS 99 µm pixel pitch detector and a compact 70kV x-ray source that allows high-definition real-time image acquisition.

The purpose of this paper is not to take away from film radiography, but to bring it into balance with radioscopy. A high-resolution gamma spectroscopy system with HPGe (High Purity Germanium) detector to determine which isotopes are present in the inspected wastes and evaluate the activity levels. YOUR CUI INSPECTION PARTNER. Real Time Radiography (RTR) Real Time Radiography (RTR) Often insulation is stripped to assess where corrosion under insulation (CUI) has developed. Daily at Radiography Site . Image appears real time on a high With dynamic radioscopic imaging the choice of an appropriate archiving method is much more difficult. Canada X-rays were first discovered by fluorescence meaning that radioscopy, or fluoroscopy as it was formerly called, pre-dates film radiographic examination. It has found extensive use in the electronics industry for the in-line examination of circuit boards, in the aerospace and automotive industries for the examination of castings and, often using gamma ray sources, in the process industry for the . Radiography achieves its very high level of stationary imaging performance through the use of high-performance X-ray equipment and X-ray film. As with radiography, small, low subject contrast features in thin sections of low density materials cause the greatest difficulty. Yet, radiography is a more widely accepted examination procedure than is radioscopy. In a properly designed radiographic or radioscopic set-up, the test object itself is the greatest contributor of Compton-scattered radiation. General radioscopic examination does not lend itself to be governed by a highly standardized procedure. With pipe diameters greater than 36" NeXray also gives the benefit of inspection others struggle with. NeXray is available in two configurations: NeXray SP (Standard Performance) and NeXray XP (Enhanced Performance). The result is that the intensity of the unwanted scatter reduces according to the inverse square of the increased distance from the image receptor to the test object, while the image intensity remains constant. , which has been utilized in several SRM experiments at PSU subject X-ray.
