WATERLOO, Ontario, Nov. 29, 2010 — Dalsa Corp. has announced its Argus platform of CCD/time delay integration (TDI)-based x-ray image scanners developed for use in the medical and dental fields.
Argus modules include high-resolution scintillation technology and standard Ethernet connectivity, allowing images to be transported directly to the host computer for processing. Assembled with advanced microelectromechanical systems fabrication techniques in the company's wafer foundry, they also provide high resolution by joining multiple silicon detectors for fields of view up to 44 cm wide.
The first product built on the platform, the Argus-PAN, incorporates proprietary and patented time delay integration technology for high sensitivity, high detective quantum efficiency and high-quality imaging at lower patient exposures.
The x-ray detector absorbs and uses as many x-ray quanta as possible to minimize the patient exposure to x-rays, while producing high resolution, contrast and image quality. The module is easy to integrate into the x-ray imaging system.
The Argus-PAN is designed for extra-oral imaging applications. The low-noise operation, coupled with a high-performance 16-bit analog-to-digital converter, provides a dynamic range of up to 80 dB. The flexible and robust module’s form factor facilitates integration into existing panoramic dental systems. The high dynamic range and sensor large full well produce high-contrast images.
Low sensor readout noise provides images with high clarity. The 100-Mb Ethernet interface eases integration into the x-ray modality, and anti-blooming preserves image integrity on the edges and in bright spots of the image.
In addition to the Argus-PAN, the line-scan TDI x-ray imaging platform supports two other modules, the Argus-DQ and the Argus-SCAN. The former features advanced scintillation technology for ultrahigh-resolution and low-noise applications like mammography. The Argus-SCAN provides a 44-cm-wide field of view suitable for applications such as body scanning and trauma imaging.
