VJT s Vi3 image acquisition and image analysis software automatically detects and evaluates defects based on user-defined inspection criteria, increasing probability of detection (POD), up-time and productivity specifications. Vi3 is a highly-customizable modular interface to adapt to custom X-ray inspection solutions. Vi3 provides a common platform to enable control of every aspect of the inspection, from motion control to image acquisition and archival. Sophisticated image processing routines, such as the ADE filter, are provided to aid in the inspection process. Vi3 also maintains an open architecture by exposing numerous interfaces to a wide range of external devices such as PLCs, database servers, etc. DICONDE compatibility enables Vi3 to be deployed at an enterprise level over multiple data-collection and review stations.

DESIGNED FOR EXTENSIBILITY Vi3 expands your hardware options since it interfaces easily with most industry-standard X-ray sources, detectors and part manipulation devices. The modular design of Vi3 allows options and functionality to be added with ease. Vi3 is highly secure due to its three levels of password protected security. Vi3 delivers ultimate flexibility by maintaining an open architecture that exposes numerous interfaces to a wide range of external devices such as PLCs and database servers. It is also DICONDE-compliant to enable it to be deployed at an enterprise level over multiple datacollection and review stations. If processes ever change at your location, Vi3 can be tuned to modify workflow or processing logic. This substantially reduces, and in some cases eliminates, the need to rewrite code. Part throughput can be maximized on a single system when tasks such as image capture, operator inspection and/or ADR analysis are run synchronously. Acquired image VI3 IMAGE PROCESSING Digital X-ray images can produce more than 65,000 levels of gray. This presents a unique challenge in data analysis and interpretation. Traditional film imaging requires multiple pieces of film to be shot at different energies, film speeds and exposure times, as well as interpretation on a light box, to bring out all the details of a part under inspection. By comparison, our digital image captures more data, a full spectrum image, for improved manipulation and enhancement. The challenge of deciphering the image is more effectively met by VJT image processing and enhancement. Some of the unique modular filters that VJT has developed include: ADE Advanced Defect Enhancement (ADE) enhances digital x-ray images contrast and brightness, optimizing clarity and definition while reducing operator fatigue. ADE enhances low contrast structures across gradients due to the different thickness of the material. Instantaneously, enhanced images show virtually all discontinuities, eliminating the need for operator adjustments. Costs are reduced through shorter inspection duration and increased consistency in operator decision- making. Inspection quality is greatly enhanced by optimized image enhancement. Enhanced image with ADE filter ADE image with noise reduction (ADE-N)
ADE-N Since ADE enhances low contrast, fine detail indications, it potentially can enhance noise present in the image too. Noise in X-ray images is typically higher when the image is acquired under low dose conditions. Reducing noise increases contrast and fine detail visibility. However, conventional noise reduction techniques using image smoothing filters tend to blur fine details along with reducing noise and are therefore not suitable. The ADE-N filter overcomes the limitations of conventional techniques by reducing noise while preserving fine details in the image. The filter integrates ADE with detail preserving noise reduction resulting in a higher signal to noise ratio, with much improved contrast and detail visibility all across the image. ADR Automatic Defect Recognition (ADR) encompasses the post-processing of images for the automatic detection of defects in pre-programmed regions of interest. ADR proprietary imaging software is used to evaluate analog and digital radiographic data without operator intervention. Regions of interest (ROI) are pre-programmed using acquired digital radiographic data. The software then analyzes each of the specified regions for defects and provides statistical process control data and may be configured to automatically alert quality process personnel when non-conforming material or process deviations exceed programmed levels. Automatic Defect Recognition can give manufacturers increased quality through repeatable, objective inspection and improved processes, but also increases productivity through decreased labor. ADR integrates the X-ray inspection process with machine vision. X-rays penetrate the product, the imaging system generates images for evaluation, and machine vision automates analysis of the image and the decision making process. DICONDE COMPLIANCE Acquired image (above), enhanced image with ADR (below) All Vi3 software is fully compliant with all DICONDE and ASTM standards. This allows users to acquire, store, archive, transmit and receive image data in a way that is universally compatible. DICONDE is an evolving standard that provides a way for nondestructive evaluation (NDE) manufacturers and users to share image data. It is based on the American College of Radiology (ACR)/National Electrical Manufacturers Association (NEMA) standard, DICOM (Digital Imaging and Communications in Medicine). The DICONDE standard encompasses all NDE specific imaging methods and technologies, such as infrared thermography, ultrasound, computed radiography, computed tomography, eddy current, and acoustic emission, and harmonizes these with the DICOM standard as unique imaging modalities.
ASTM STANDARDS The ASTM standards represent a complete and comprehensive information source for users and manufacturers. These standards assist manufacturers with the standardization of measurements and reporting of DDA properties that help users make informed decisions on purchasing decisions. They also assist user introduction of the DDA technology into their operations for almost any inspection application and provide tests and methods to establish and track baseline performance. VJ Technologies Vi3 brings a complete detector performance package which is easy to use for the operators but yet has very powerful tools for the managers. The detector performance software uses VJ Technologies unique approach to fully configurable software. This allows for easy configuration changes based on different customer preferences. All ASTM tests are performed in a Wizard like process. When an X-ray is remotely controlled, all ASTM image captures are done automatically (no operator intervention except to place phantom in front of detector). All test images are captured first and then automatically presented to the operator for testing. The operator is walked through each test function. All tests are then archived using a Microsoft SQL database. With a detector life history contained in the database, users are able to track detector degradation giving much better end of life predictability. Along with the data, all images used for an evaluation are archived. Images are then attached to the database record containing the test evaluation. All ASTM pass\fail test criteria is automatically loaded. Most, if not all, aspects of the ASTM tests are controlled automatically. This is very important for test repeatability reducing the risk of operator error. Image corrections are automatically turned on or off depending on test requirements. ASTM tests are preformed in a Wizard like process, and the operator is walked through each function
