CR/DR systems get smaller, easier to use


Having promised and largely delivered cost savings and increased efficiency, vendors of CR and DR are stepping up efforts to smooth the transition to digital, focusing on flexibility and ease of use. System manufacturers are designing products for every segment of the imaging environment from full-scale general radiography suites to point of care, automating the process of image acquisition, and implementing advanced technologies that improve image quality. At the 2005 RSNA meeting, vendors highlighted manageability, displaying systems that can rest on a desktop or move from room to room as well as products that can capture a wide variety of projections with a minimum of manual adjustments.

Agfa HealthCare

In addition to the classic x-ray film, hard-copy solutions, RIS/PACS, and speech technology markets, Agfa HealthCare is active in computed radiography. After revamping its product line last year by renaming and upgrading the CR 25.0, 50.0, and 75.0 systems for centralized and decentralized environments, Agfa introduced this year the DX-S for point-of-care CR in general radiology, pediatrics, and the emergency department. DX-S makes use of DirectiX needle-based detector technology to create a crystal matrix that reduces light spread in the scintillator layer, thereby minimizing scatter and sharpening sharp images. DX-S also employs line-to-line Scanhead technology, which accelerates throughput.

  • DX-S, capable of processing 120 to 180 plates per hour, provides precise image quality up to 10 pixels/mm or 5 line pair/mm. The product has a small footprint, measuring 12.6 x 30.7 x 33.4 inches in size and weighing approximately 150 pounds.


Privately held Alara, which produces dental, medical, and nondestructive testing systems, moved into CR two years ago with the launch of its CRystalView compact CR system. The desktop system was cleared by the FDA in October 2003.

  • The compact CRystalView R 2000 weighs 120 pounds and measures 26 x 32 x 15 inches. The system processes more than 50 plates per hour for 14 x 17-inch cassettes at a resolution of 6 pixel/mm. It scans smaller cassettes at a rate of 60 to 66 plates per hour and a resolution of 9 pixel/mm.


After introducing the SyneRad MULTI freestanding single selenium detector system in 2004, Anexa followed with the SyneRad OMNI/OMNI RT in 2005. A DR system with a selenium-based detector, SyneRad OMNI is available as a freestanding single detector for the emergency department or as a dual detector with a fixed table.
