Computer-aided detection is moving into high-visibility mammography and DR systems, as imaging heavyweights form development and distribution alliances with CAD vendors. Amid these corporate moves, developers of CAD continue to advance the technology.
Computer-aided detection is moving into high-visibility mammography and DR systems, as imaging heavyweights form development and distribution alliances with CAD vendors. Amid these corporate moves, developers of CAD continue to advance the technology. Exhibitors at the RSNA meeting showed investigational products that adapt CAD to imaging modalities such as CT to evaluate lung nodules and colon polyps for the presence of cancer, and MR to help interpret MR mammograms.
CADx Medical Systems
Since the Second Look CAD system was approved by the FDA in February, CADx Medical Systems has strengthened its position in this growing market. It has done so through a merger with long-time research and development partner Qualia, the release of Second Look version 4.0 software, integration with the PenRad Mammography Information System, purchasing agreements with major resource and imaging utilization management companies, and development/distribution alliances with Fischer and Lorad. At the RSNA meeting, CADx announced a partnership with GE and unveiled remote CAD mammography as well as CAD CT for the lung and colon.
Specializing in radiology informatics systems that enhance workflow, data analysis, and quality control, Confirma announced its first CAD product, CADstream.
Capitalizing on its relational database platform, iCAD integrates CAD into existing or planned informatics systems, digital imaging resources, and workflow.
Developer of CAD software for the ImageChecker processing and visual display system, R2 has installed products in more than 700 facilities to interpret more than five million mammograms to date.
In keeping with its specialty in CAD systems optimized for breast cancer screening, Scanis introduced the newest versions of Mammex TR and Mammex MammoCAD.
Seeking to expand its repertoire beyond film digitizers, Vidar Systems is combining its core technology with that of CAD.
PET/CT dominates new offerings with iterative step to 16 slices
Major vendors picked up where they left off last year in the development of hybrid PET/CT systems, extending technology to its furthest capabilities or tweaking existing products for specialty applications. Premium performance 16-slice CT scanners were added to PET scanners, either as commercial products or on the drawing board, and a compact PET/CT optimized for oncology was displayed. The goal behind each was simple: to improve efficiency either by reducing scan time or conserving space and lowering cost to the customer.
The company, a longtime leader in PET development, albeit behind the scenes as a supplier to Siemens, is determined to step from behind the curtains with its own products while maintaining its fruitful relationship with the German vendor. CTI also designs and manufacturers cyclotrons and PET chemistry systems.
Gamma Medica Instruments
The company targets niche markets with its line of LumaGem scintillation cameras. A primary focus is women's healthcare.
GE Medical Systems
Only a few years ago, GE was struggling to be taken seriously as a major vendor of nuclear medicine equipment. Corporate acquisitions of SMV and the nuc med assets of Elscint, along with a renewed focus on PET, have helped make the company one of the premier players in the segment.
Hitachi Medical Systems America
Hitachi entered the PET marketplace in 2002 with the Sceptre PET system, a value-priced PET scanner sourced from CTI PET Systems. The product, introduced at the June meeting of the Society of Nuclear Medicine, comes with the Avia fusion workstation.
Philips Medical Systems
Building on successes engineered by ADAC Laboratories, which it acquired in 2000, Philips continues to provide one of the most extensive lines of gamma cameras and PET scanners in the industry.
One of the first companies to develop commercial PET systems, Positron continues as a single-modality vendor of positron technology. The company showcased its air-cooled mPower whole-body scanner, which supports neurology, cardiology, and oncology exams. The scanner was introduced at the 2001 RSNA meeting.
Siemens Medical Systems
Once the undisputed leader in nuclear medicine, Siemens fell behind upstart ADAC in the mid-1990s, only to become a market leader again at the turn of the century with the success of its e.cam gamma camera and PET/CT biograph. Siemens supplies its core technology gamma cameras and workstations to Toshiba for private labeling.
Long a leader in PET pharmaceutical distribution, Syncor also provides ancillary technology useful in the practice of nuclear medicine.
Toshiba America Medical Systems
Through its strategic alliance with Siemens, Toshiba America provides its own version of the e.cam gamma camera, dubbed T.Cam. Toshiba mirrored developments by Siemens, displaying its e.soft Signature Series workstation for the T.Cam variable-angle, dual-detector gamma camera, which is designed to deliver high performance and efficiency.
