As the digital revolution continues to sweep across the
radiology landscape, many technology manufacturers have released
new first- and second-generation digital radiography (DR) and
computed radiography (CR) products. Several of the CR/DR products
previewed at RSNA 2002 have become commercially available in recent
Canon adds two
products to DR line
Canon U.S.A., Inc. (Lake Success, NY) recently received FDA
approval for two new additions to their DR line: the CXDI-50G
Portable Digital Radiography System and the CXDI-40C Premium
Digital Radiography System.
The CXDI-50G is a portable digital radiography system with a 14-
* 17-inch detector. The unit, which is large enough for chest and
abdominal X-rays, weighs <11 lb and is <1 inch thick.
Designed for use as a bedside examination tool, especially in
trauma situations, it can also be used for applications that may be
difficult to perform with a fixed device.
Total image processing time is 20 seconds, with preview images
available in 3 seconds. The amorphous silicon flat-panel sensor has
a grayscale of 4096 and approximately 6 million 160-micron pixels.
Built-in software allows for connectivity to picture archiving and
communication systems (PACS), radiology information systems (RIS),
or any DICOM printer.
The FDA has also approved the company's new flagship DR system,
the CXDI-40C. Designed for most general radiographic applications,
the unit features a 17- * 17-inch imaging area with an amorphous
silicon flat-panel sensor with a cesium iodide (CsI) scintillator,
a high detective quantum efficiency (DQE), and a high film speed
(equivalent to ISO 400). It is available in both wall-stand and
The Canon Control Station stores captured images and displays
preview images on a touch-sensitive wall-mounted operation panel.
The system also includes DICOM-based networking capabilities.
These additions to our DR product line display Canon's
commitment to advancing medical imaging technology and expanding
the scope of digital radiography, said Eric Kuramoto, director and
general manager of the medical systems division. The Canon CXDI-50G
provides a wider range of DR applications than ever before. We
believe it provides customers with all the reasons they are looking
for to make the move to digital radiography.
Fuji introduces multicassette CR
Fujifilm Medical Systems USA (Stamford, CT) recently introduced
the latest addition to its CR line: the ClearView-CS (Figure). This
new reader offers a multicassette stacker design, providing
multiroom capability. The system also includes dual-sided reading
technology. With this technology, the captured X-ray information is
read simultaneously from both sides of the imaging plate, resulting
in 100% higher DQE, and lower noise. The spatial resolution
sampling is 50 microns for both 18- * 24-cm and 24- * 30-cm
The ClearView-CS can process up to 178 imaging plates per hour
and can be upgraded for mammography applications, processing up to
20 screening mammography exams per hour from multiple examination
The introduction of ClearView-CS is a testament to Fuji's
ongoing commitment to provide customers with the most advanced
digital X-ray solutions, said John Strauss, director of marketing,
imaging systems at Fuji. The addition of this reader extends our
comprehensive, technology-consistent product array.
The ClearView-CS is expected to be commercially available in the
fall of 2003.
Orex debuts CR with
Orex Computed Radiography (Auburndale, MA) recently added a
fully integrated mini-PACS to its line of desktop CR products. The
Orex/Onyx-RAD allows users to send and receive DICOM files and burn
CDs at the CR reader. The viewer includes advanced features such as
pan, zoom, and annotate, and a proprietary unsharp masking feature
provides edge enhancement. The unit is Internet- and
Intranet-enabled to permit remote image transfer; lossless and
various lossy compression levels are available.
When combined with one of the Orex distributed computerized
radiography (D-CR) systems, Onyx-RAD mini-PACS provides PC-based
quality control, review, and advanced image management in a compact
With tabletop formats and the ability to process up to 84 plates
per hour, the Orex D-CR line was designed to address the needs of
freestanding radiology clinics and medical professionals whose low
imaging volume does not justify the cost and space requirements of
large central units. At present, the D-CR line includes the
single-cassette PcCR 1417 and the dual-reader RAIS 2 (Redundant
Array Integrated System). The PcCR 1417 reads up to 41 plates an
hour up to 14 * 17 inches, while the dual system reads 84 plates an
hour. Both are available with built-in Onyx-RAD.
Ceiling-mounted C-arm with flat-panel detector from
Siemens Medical Solutions (Malvern, PA) recently unveiled a new,
fully digital ceiling-mounted cardiac imaging system equipped with
flat-panel detector (FD) technology. The AXIOM Artis dTC has an
optional integrated ultrasound solution and a multimodality
display, permitting the visualization of ultrasound, computed
tomography, and magnetic resonance images on the system. The unit
employs the company's proprietary syngo technology, providing full
DICOM compatibility and integration with hospital information
systems (HIS) and RIS.
The AXIOM Artis dTC also includes the new CareShuttle transport
system, designed to eliminate repositioning of the patient in the
exam room. The patient is prepared and transported to the
cardiology system on a single tabletop that is then docked to the
system table. Vital signs can be monitored continuously during
transport and intervention.
The ceiling-mounted C-arm, combined with the compact FD
technology, allows for access to virtually all anatomic regions.
System controls can be accessed via the tableside touch-screen
Flat-panel detectors not only improve image quality, but, in
combination with the ceiling-mounted design, also significantly
improve access to the patient for cardiac procedures, said Manfred
Fink, vice president of the X-ray and angiography unit at Siemens.
The high resolution obtained allows the user to visualize even the
finest vascular structures and stents in precise detail.
Kodak begins shipping CR 850
Eastman Kodak Health Imaging (Rochester, NY) has begun
commercial shipment of its latest CR system, the DirectView CR
This single-cassette system offers a throughput of up to 100
cassettes per hour. Designed for use in areas with limited floor
space, such as the emergency department or the intensive care unit,
the CR 850 has a footprint of 25 * 29 inches (63 * 73 cm). Its
privacy features include user identification and authentication,
display blanking, and automatic user logout.
The system includes a 15-inch flat panel display and a barcode
reader for patient and cassette identification.
The new system supports the company's DirectView remote
operations panels, which allow patient/cassette identification,
image review, and image distribution to be performed in the
examination room, and the optional enhanced DirectView EVP
software. It also supports the company's new long-length imaging
system. An optional software package allows users with Kodak
DryView laser imaging systems to print a true-size segment from
anywhere within a composite long-length image and to print up to 4
true-size segments to form a composite long-length film image up to
129 cm in length.
