DALSA to Exhibit X-ray Detectors for Dental and Medical Imaging

RSNA-2010-Radiological socitey of North America annual meetingDigital image sensing technology developer DALSA will be showcasing its Argus platform of CCD/TDI x-ray scanners as well as a new family of CMOS detectors at the 2010 RSNA. Argus modules include high resolution scintillation technology and standard Ethernet connectivity, allowing images to be ported directly to the host computer for image processing. Assembled with advanced MEMs fabrication techniques in DALSA’s own wafer foundry, they also provide unmatched resolution by joining multiple silicon detectors for large fields of view up to 44 cm wide.

More about DALSA’s Argus Platform.

The first product built on the Argus platform, the economical Argus-PAN, will be showcased at the upcoming RSNA, which will be held Nov. 28 – Dec. 3, at McCormick Place in Chicago. DALSA will showcase its latest advances in image sensor technology for medical imaging and dental radiography in the North Building; Hall B; Booth 8722.
The Argus platform incorporates DALSA’s patented TDI (Time Delay and Integration) technology for high sensitivity, unmatched detective quantum efficiency (DQE) and incredible image quality at lower patient exposures.

“A good X-ray detector has to absorb and utilize as many X-ray quanta as possible in order to minimize the patient exposure to X-rays, while producing the highest resolution, contrast and image quality. DALSA’s new cost-effective Argus platform provides such performance in a module that is easy to integrate in the X-ray imaging system,” said Behnam Rashidian, Argus product manager.

The Argus-PAN is designed for extra-oral imaging applications. The extremely low noise operation, coupled with high performance 16-bit ADC, provides up to 80dB of dynamic range. Primary Argus-PAN features include:

  • Assembled with advanced MEMs fabrication techniques for high resolution and large fields of view up to 44 cm wide.
  • Flexible and robust module form factor for ease of integration into existing panoramic dental systems.
  • High dynamic range and sensor large full well enables high contrast images.
  • Low sensor readout noise provides images with high clarity.
  • 100 Mb Ethernet interface for ease of interface to the X-ray modality.
  • 16bit ADC for high precision image capture.
  • Anti-blooming, preserves image integrity on the edges and in bright spots of the image.

Other DALSA’s Argus Products.

In addition to the Argus-PAN, the Argus line scan TDI X-ray imaging platform will support two other modules, the Argus-DQ, and the Argus-SCAN. The Argus-DQ features an advanced scintillation technology for ultra-high resolution and low noise applications like mammography. The Argus-SCAN will provide an extremely wide 44-cm-wide field of view ideal for applications such as body scanning and trauma imaging.

In addition, the developer will be introducing its new Xineos-1313 family of CMOS flat-panel detectors for fluoroscopy and cone-beam CT (CBCT) dental Imaging.
DALSA developed Xineos to deliver superior sensitivity and signal-to-noise performance compared to other standard technologies at equal X-ray dose conditions. CMOS image detectors offer numerous advantages including the ability to record faint image details at higher resolutions–allowing for the diagnostics of medical anomalies at earlier stages, and significantly increasing the probability of early intervention, patient recovery, and reduced treatment costs.

“With the introduction of DALSA’s Xineos line of digital imaging X-ray panels, we are leveraging our CMOS technology to maximize the signal and minimize sources of noise in X-ray imaging,” stated Bryan Delodder, Xineos product manager at DALSA. “In low dose conditions where competing products fail to distinguish faint signals due to noise, our advanced CMOS detectors excel to deliver the clearest images possible.”

In dental applications DALSA’s Xineos-1313-EO is designed to operate at full resolution for both frame-based panoramic imaging, at frame rates exceeding 300 fps, as well as for medium field of view (MFOV) CBCT applications at 30 fps. An optional “Sequence Memory” enables storing an entire CBCT image sequence inside the detector, eliminating the need for rescans due to data acquisition loss during the actual CBCT scanning procedure.

In medical applications the Xineos-1313-FL is optimized for fluoroscopic imaging, offering the highest X-ray sensitivity combined with lowest readout noise. Xineos enables real-time imaging for cardiac, vascular, orthopedic as well as other minimally-invasive procedures that depend on real-time imaging, with minimum patient dose.
Xineos products are equipped with DALSA‘s hardware and software implementation of the industry standard GigE Vision data interface. Xineos can connect almost any computer within minutes to produce low-noise, real-time, high-resolution X-ray images.
