Tabletop scanning for all types of flexible phosphor imaging plates
- Compact, but expandable
- Reduced exposure time, high-quality images
- Scan multiple plates, side-by-side or back-to-back
The CRxVision scanner’s wide latitude — a result of 16-bit image processing at 35/70 microns resolution — eliminates the need for multiple gain settings when exposing over a wide range of thicknesses.
General Electric’s Measurement and Control business introduced a computed radiography (CR) capability with its high-throughput CRxVision scanner — a tabletop system developed for critical-quality welding inspection. In addition to qualifying welds according to prevailing weld-quality standards (including ISO 17636-2 Class A and B, ASME, ASTM and EN) the CRxVision reportedly is versatile enough to for many other NDT applications.
The new scanner can be used in ambient light conditions and has a light cover that protects the plates from light exposure during scanning.
The scanner is compact and portable, weighing less than 99 lb (45kg) with a footprint of 22 x 22 inches (560 x 560 mm). The unit extends to 22 x 50 inches (560 x 1,280 mm) when the feed and exit trays are attached. It is designed to fit through a 23-in. (584-mm) door for mobile darkroom use.
CRxVision is described as a flexible and productive way for industrial customers to increase throughput and extend plate life. The scanner reduces exposure time and provides high-quality images, according to multiple design details and compatible software. The former includes a particularly wide latitude that eliminates the need for multiple gain settings when exposing over a wide range of thicknesses. This result from 16-bit image processing at selectable 35 or 70 microns resolution.
The CRxVision achieves high throughput — 90 plates/hr. at 70 microns; or, 28 plates/hr. at 35 microns for a 10 x 40 cm (4.5x17-in.) plate — because it is equipped to scan multiple plates, side-by-side or back-to-back, resulting in high throughput. It has the ability to scan imaging plates of any shape or size, from 0.75 to 60 inches (20 to 1500 mm) in length. The system’s flexible imaging plates will exhibit no curl after bending around small pipe diameters, according to the developers.
CRxVision employs a magnetic transport system, so the sensitive phosphor side of the imaging plates is not touched during scanning, which promotes longer service life for plates.
In addition, GE’s updated DICONDE-compliant Rhythm RT software includes an automatic image cropping function that optimizes workflow efficiency. A light cover protects the plates from light exposure during the scan cycle allowing use in ambient light conditions.
New, high-efficiency laser optics promote better image quality at lower radiation doses. The system provides “equal or better” exposure times for welds than conventional film does, according to the developer.
“GE continues to invest in its digital conversion product line for the oil and gas, aerospace and other industries,” according to Juan Mario Gomez, general manager for Radiography with GE’s Measurement & Control business.
“GE’s advanced approach to improve the efficiency of the inspection process, while surpassing competitive image quality ensures our customers have advanced technology in hand,” he added.
