X-ray, radiology's bread and butter, is very much back on the radar screen of smart physicians and administrators seeking to improve imaging quality while streamlining workflow and productivity. With market penetration reaching only 2 percent for digital x-ray systems, there's a lot of room for growth. Market growth numbers are sighting about 15 percent next year as well. Prices that originally could only be paid by large facilities are coming down so that small to medium-sized hospitals and imaging centers are now investing in DR as well as older and very versatile brother, computed radiography.

A variety of new digital x-ray systems, both CR and DR, and enhancements to existing units debuted at RSNA. The majority are coupled with PACS, but not always as facilities invest at the pace they can.

The features show-goers honed in on are signal-to-noise ratio, detective quantum efficiency and spatial resolution, as well as overall speed, efficiency and cost-effectiveness for the business-minded.

Analogic Corp.
debuted a new multipurpose, direct digital radiography (DR) system, SyneRad, the gained FDA marketing clearance just before showtime.

The system features the new GR17 amorphous Selenium flat-panel detector, which was developed by Analogic's Canadian subsidiary, Anrad Corp. Designed and developed by Analogic, the new SyneRad OMNI DR system is being sold by ANEXA Corp., an Analogic subsidiary, which sells digital imaging products directly to end-users in select U.S. markets. The system was designed for emergency medicine and orthopedic applications.

ANEXA's SyneRad OMNI with SELENIUM2 detector technology provides multi-frame acquisition capability in full 17 x 17 inch fields, allowing it to perform joint stability and motion studies, the company said.

Canon Medical Systems showcased its full range of DR systems at RSNA that feature its amorphous silicon (a-Si) flat-panel sensor.

Canon's CXDI-40G general DR system with multiple wall stand and table configurations is designed for a wide range of general radiography applications. The system can capture 17 x 17-inch x-ray images from almost any position or angle, the company said. The DR system includes a Bucky table, upright tilting wall stand, universal stand, and a ceiling suspended multi-positioning unit.

The CXDI-40C is coined as Canon's premium DR system. The CXDI-40C features a 17 x 17-inch imaging area and is designed for most general radiographic applications. Versatile and flexible, it comes in multiple wall stands.

In the portable arena, Canon highlighted its CXDI-50G Portable DR System. The CXDI-50G is designed for applications extending from trauma to bedside exams. It has a 14 x 17-inch imaging area and weighs 10.6 lbs. With a large imaging area and lightweight design, the CXDI-50G extends the range of exams possible with DR. It is large enough for chest and abdominal x-rays. But the compact design also makes it as easy to position as a conventional film cassette or CR imaging plate when performing lateral or axial imaging of limbs and other areas, the company said.

The CXDI-31 can be freely positioned, just like conventional screen-film cassettes. It is designed to capture images at angles that are difficult to get with fixed devices and supports lateral and axial imaging of limbs, shoulders, the skull, neck, and extremities. The CXDI-31's high-resolution makes it perfect for neonatal and pediatric applications.

The company has installed about 1,700 DR units to date.

CMT Medical Technologies presented two new families of DR products at RSNA, the SmartRAD and SmarSPOT PrimaX.

The SmartRAD family includes the SmartRAD Elite single- detector, upright system for chest applications, the SmartRAD OmniX single-detector multipurpose universal arm system for all radiographic exams and the SmartRAD GeminiX dual-detector system for a full range of radiographic exams, fast and easy operation and high patient throughput. The full family is available for sale worldwide.

The SmarSPOT PrimaX high-resolution digital photospot and angiography imaging system is designed for the retrofit market. The system is compatible with any existing vendor room, increasing the department efficiency by at least 30 percent for highest throughput while reducing significantly exposure to radiation both for patients and operators, CMT said. Availability is expected in the first quarter.
