Dynamic CMOS Flat X-Ray Detectors Designed for Interventional Procedures

Radiation-hard detectors with improved dose performance and extended dynamic range provides switchable saturation dose, low dissipation power and built-in gain, offset and defect correction, a range of radiation-hard detectors are versatile, effective, and easy to integrate.

Teledyne Dalsa (Waterloo, ON, Canada), a Teledyne Technologies company and developer of digital X-ray image sensing technology, presented four new dynamic detectors at the Radiological Society of North America (RSNA) 2014, November 30 to December 5, 2014, in Chicago (IL, USA). The advanced detectors with fields-of-view (FOV) of 20 x 22 cm, 22 x 22 cm and 30 x 30 cm, together with earlier models with dimensions of 13 x 13 cm and 15 x 15 cm, complete the Xineos range of real time, low dose complementary metal-oxide semiconductor (CMOS) flat X-ray detectors. Xineos detectors are targeted at interventional procedures and are well-positioned to replace the incumbent imaging technology of thin-film transistor (TFT) flat detectors and image intensifiers of up to 30.48 cm in size.

The new Xineos models, including the 2222HS, 3030HS, 2022HR, and 3030HR, utilize Teledyne Dalsa’s sixth-generation proprietary radiation-hard CMOS active pixel design and are the industry’s first flat detectors to not only surpass the low-dose performance of image intensifiers but also combine this industry benchmark with the form factor advantages of traditional amorphous silicon flat panels. Offering switchable saturation dose, low dissipation power and built-in gain, offset and defect correction, Xineos detectors are versatile, effective, and easy to integrate.

The high speed Xineos-HS detectors, featuring 152 μm pixel size, are designed to meet the demanding needs of both surgical and cardiovascular procedures by combining high dynamic range with unsurpassed signal-to-noise performance and real-time imaging at the lowest exposure levels in full resolution at up to 90 fps. Additionally, the detectors with square FOV of 22 x 22 cm² are the largest commercially available 9-inch flat detectors to benefit spinal surgery.

Xineos-HR is the high resolution line of detectors, featuring pixel size of 99 micrometers, designed to meet the versatile needs of clinical, scientific and industrial applications. These detectors are capable of 30 fps real-time imaging at full resolution of up to 5 Mpixels or 9 Mpixels for the 9-inch or 12-inch detector sizes, respectively. Flexible zoom modes can be used to capture regions-of-interest at 120 fps or even faster.

“Xineos CMOS detectors enable improvement throughout the entire healthcare chain—in diagnostics, in patient care, and in their return on investment,” said Dr. Mila Heeman, senior marketing manager at Teledyne Dalsa. “Our detectors allow physicians to expand the boundaries of imaging.”

Teledyne DALSA exhibited the following CMOS and charged coupled detector (CCD) X-ray detectors at RSNA: (1) Xineos-1313 and Xineos CMOS flat detectors provide low dose diagnostic image quality at full resolution and in real time. There are two versions: high dynamic range and high sensitivity. (2) The Xineos-1515 features streamlined switchable saturation dose for combining high dynamic range and high sensitivity in a single device. (3) Argus scanning CCD-TDI X-ray detector platform is designed for mammography, general radiography, and dental panoramic and cephalometry applications. (4) The Helios isoptimized for mobile applications, and features a large CMOS active imaging area of 20 x 25 cm2 (8-inch x10-inch) while maintaining excellent image resolution with a pixel size of only 96 micrometers. (5) The Shad-o-Box 6K HS is a high resolution CMOS detector with 50 μm pixel pitch and dimensions of 11 x 14 cm targeted at biopsy analysis, and other scientific and industrial applications. (6) Lastly, the Rad-icon 1520 is a new high resolution large area CMOS detector featuring high speed low dose seamless switchable saturation dose and 99 μm pixel in 15 x 20 cm dimensions.
