<b>Radiography Today</b> Digital radiography has the potential to reduce costs in a variety of medical applications, and the latest wave of analyzers, X-ray systems and measuring systems put it to the test. Digital radiography continues to see new innovations as the field rapidly evolves. With its ability to maximize time, reduce radiation and to digitally transfer and enhance images, the technology’s value is unmistakable. Many applications benefit from its use, such as 3-D measurements, imaging and computed tomography. The following products represent some of the latest breakthroughs in the industry today. <b>Innov-X Systems Inc.</b> (www.innovx. com/products/delta) announces the Delta line, a new breed of handheld XRF analyzers. The Delta analyzers are fully ruggedized to industrial standards— including no PDA or movable display— while providing analytical performance and testing speed. They can take hundreds of tests per day with increased analytical confidence. The analyzers have a rugged industrial- grade body; superior balance and ergonomics with over-molding and rubberized grip; rear-facing touch-screen display for visibility in bright or dim conditions; and external heat-sink engineered for extreme temperature and continuous high-power use. They also feature true hot-swap battery capabilities; fast measurements for high throughput; and redesigned geomet r y for outstanding analytical performance, speed and lower detection limits. The line also has an auto-cal ibrating, auto-charging docking station. Reply 36 The Delta analyzers are fully ruggedized to industrial standards—including no PDA or movable display. To further extend the reach of computed tomography applications, Nikon Metrology (www.nikonmetrology. com) introduces a wider range of X-Ray source power and targets. Microfocus X-Ray sources offer higher power and superior cooling boost X-Ray flux, allowing for the inspection of denser and larger industrial objects, such as large castings and single-crystal metal alloy turbine blades. By using X-Ray spot sizes orders of magnitude finer than competitive mini-focus sources, end users benefit from superior resolution and accuracy, and a wide array of measurable parts. In combination with a proprietary curved detector that minimizes X-ray scatter, the Nikon Metrology XT H 450 system provides 25 micron accuracy when measuring the internal geometry of turbine blades. Reply 37 The new Metrotom 800 computer tomograph from Carl Zeiss (www.Zeiss.com/imt-products) was specifically developed for 3-D measurements and structural inspections of complex parts made of plastic, composite materials and ceramic. With the help of metrotomography— the combination of metrology and tomograph—this measuring system enables both the dimensional measurement of the geometry and the inspection of the interior structure of parts up to 150 millimeters. The maintenance-free X-ray technology results in extremely low maintenance costs and thus minimal downtimes, and the small focal point of the X-ray sourceGenerates razor-sharp projection images on the detector. The high physical resolution of the X-ray detector of around three million pixels enables very high detail recognition. Metrotom 800 achieves measuring accuracy of 4.5 ìm + L/100. Through the use of polymer concrete for the enclosure, the use of lead can be largely avoided. Reply 38 <b>Alara </b>(www.a lara.com/products / cr.html) is pleased to introduce CrystalView R200, a high quality computed radiography system for single plate CR reader applications. CrystalView has daylight operation, integrated read/erase and throughput of 50+ plates per hour. It accommodates one or more separate quality control workstations. Imaging plates are housed in industry-standard sized cassettes of various sizes. The system is designed to be interfaced to an operator’s imaging network so that scanned images may be forwarded to a printer or server for reading at review stations. The system may also be operated stand-alone. The system may be readily interfaced to existing PACS systems that conform to these standards. CrystalView is an ideal lower cost CR reader for CCU, ICU, ER applications where quick readout of portable X-ray images is desirable, with immediate forwarding to the radiology PACS system for review by radiologists. Reply 39 <b>Env i sion CmosXray ’s</b> (www.Cmosxray.com) CMOS digital X-ray system employs the highest resolution detectors. Utilizing an extensive imageSoftware package, combined with seamless conveyor control, EnMotion is a real-time X-ray system for production inspection in today’s market. Automatic defect recognition is an available option. The system can be used in castings, trays of parts, assemblies, composites, tubing, agricultural products, ordinance, food and pharmaceuticals. Reply 40 <b>Canon</b> (www.usa.canon.com) introduces the CXDI-70C Wireless Digital Radiography System. The system features a 14-inch by 17-inch image area, an ISO 4090 film cassette of the same dimensions, and a cable-free image transfer. The new wireless detector weighs 7.5 pounds, which is the lightest wireless detector in the industry to-date, the company says. The system provides medical practitioners with greater device portability and extraordinary image quality. Building upon the success of the CXDI-55G/55C in the high-performance digital radiography systems market, the CXDI-70C helps deliver fast, reliable high-resolution images. It also incorporates a new glass substrate with a pixel pitch of 125 microns. Despite realizing a higher resolution as compared with the company's current 160-micron pixel pitch digital radiography systems, the new model delivers an increased level of sensitivity. In addition, the unit features a Cesium Iodide scintillator, which delivers high-quality images while reducing the X-ray exposure to the patient. The CXDI-70C Wireless DR System is an ideal solution for all of radiography systems, including mobile systems. Reply 41 <b>MultiTest System Advantage</B> Korea-based Korean H Co. Is a manufacturer of touch screens used for mobile, navigation and portable media player applications. The company wanted to know the actuation force of the touch screen, used in a navigation device, to ensure proper manufacture and a consistent high quality end product for their customers. Their main priority was to establish that the screen required a uniform level of pressure to activate controls. Mecmesin supplied a MultiTest 1-i computer-controlled test system, combined with an intelligent loadcell, an adjustable X-Y table and compression probes. The touch screen is fixed onto the X-Y table, which allows fine precision alignment of the touch screen underneath the loadcell and compression probe. This enables operators to easily move the touch screen in line with the different test points to measure the uniformity of actuation force across the screen. For better accuracy of results, a lower capacity of loadcell is used for this application. The compression probe is lowered and raised at different force levels to determine the range of forces required to ensure reliable operation of the touch screen. <b>Resolution and Accuracy</B> A decisive factor in the company’s decision to buy the system was the software’s event input facility, enabling signals from external devices to be incorporated into its Emperor software. In this case, the touch screen is monitored to register when a switch is activated during the compression test, thereby providing reliable information regarding the actuation forces involved. The MultiTest 1-i provides a powerful and comprehensive testing system for force measurements up to 1 kilo-newton. With full programming capability and a large selection of analysis options, the MultiTest 1-i offers unparalleled test versatility. The system is combined with Mecmesin’s high performance loadcells, ensuring excellent resolution and outstanding accuracy. The system features compression and Tension testing with a maximum load of 1 kilo-newton. It has crosshead movement up to 500 millimeters and space to fit a sample of 590 millimeters. Its maximum sample diameter is 134 millimeters and it has nine different loadcell capacities from 2 newtons to 1,000 newtons. The system has a load resolution of 1:6500 and load accuracy of plus or minus 0.1% of full scale. It has a speed range of 1 to 500 millimeters per minute. It weighs 19 kilograms. The system offers full control over test program and analysis, and boasts a user-friendly graphical interface. All calculations can be performed at the touch of a button, and the system has an IP splashproof membrane control panel.
