PACS companies jockey for position at RSNA show

Many vendors to display Windows NT and Web technology

You can finally believe the hype. With physician interest at last matching the enthusiasm of PACS vendors, this month's Radiological Society of North America meeting figures to be another banner event for companies active in the fast-growing digital image management market.

As might be expected in a rapidly expanding industry, the impact of consolidation will be evident on the McCormick Place exhibit floor. Several PACS companies either merged with or acquired other players during the year to solidify their positions, with Imation's acquisition of Cemax-Icon and GE Medical Systems' purchase of Lockheed Martin's PACS unit among the most notable events in 1997.

Smaller PACS players that aren't participating in the mergers and acquisitions frenzy are seeking new OEM relationships to maximize their distribution channels. With larger firms looking to outsource portions of their PACS line to speed product launches, small companies will continue to fill a need in the market.

On the technology side, the Windows NT operating system continues to grow in prominence, due to its flexibility and customers' familiarity with the Windows user interface. Several vendors will display work in porting their PACS product lines to the Microsoft platform.

The use of World Wide Web protocols to disseminate images and information will again assume a prime position in many booths. Low-cost Web browsers are viewed by many customers as an excellent way to secure enterprise-wide acceptance of PACS technology.

Another trend on the exhibit floor will be the growing number of vendors showing developments in integrating PACS with hospital and radiology information systems. Many industry analysts believe that these integrated image and information systems represent the future of the PACS market.

Access Radiology

Access of Natick, MA, will introduce a range of products employing the firm's Framewave wavelet compression algorithms. The company will highlight its work-in-progress DxWave Web-based image transmission product (PNN 7/97), which will also employ wavelet compression. Archiving software using wavelet compression algorithms will also be demonstrated. Physicians interested in examining the effects of various compression algorithms on medical images will be able to do so in a demonstration area in the vendor's booth.


Ultrasound powerhouse Acuson will emphasize the porting of its Aegis ultrasound miniPACS network to Windows NT (PNN 6/97). Acuson decided to move away from the Macintosh platform because of the popularity of Windows NT among IS departments, as well as concerns over the longevity of the Macintosh line, according to the company. Shipments of NT-based versions of Aegis are slated for the second half of 1998. The Mountain View, CA-based company will also feature its WebPro Web interface for Aegis.


Agfa will introduce Release 3.5 of its Impax software, which includes parallel database technology, an automated teleradiology reporting feature, and support for digital linear tape backup archives.

Also taking a prominent place in Agfa's booth this year will be Web 1000, the company's Web-based image distribution product. Web 1000 allows clinicians to receive radiology reports and call up images from an archive. To speed data transfer times, Web 1000 employs a lossy wavelet compression technique, but users can also pull up a specific region-of-interest with a lossless algorithm to ensure full image quality. Since Web 1000 is integrated directly into Agfa's Impax PACS line, company officials believe it offers advantages over other Web products.

Algotec Systems

Raanana, Israel-based Algotec will introduce MediLink, a DICOM- and HL-7-compliant interface engine that links Algotec's PACS offerings with other healthcare information systems. The vendor will also emphasize MediStore, a multitier, multimedia clinical image and data repository. MediStore supports configurations ranging from gigabytes of RAID online storage to terabytes of archiving capacity on DLT jukeboxes, according to the company.

ALI Technologies

Ultrasound miniPACS developer ALI will feature the next release of its UltraPACS ultrasound miniPACS network. Including JPEG or RLE compression and a component-level DICOM interface network, UltraPACS is available on Unix or Windows NT/95 operating systems.

Ultrasound won't be the only modality represented in ALI's booth, however. Several multimodality products will be displayed, including an image management workstation, an online diagnostic reporting system, and a work-in-progress multimodality DICOM-based PACS archive. The company will also exhibit its DICOM WinView viewing software package for PCs.


Cerner of Kansas City, MO, will show a version of its ProView software package designed to run on the company's HNA Millennium network architecture (PNN 10/97). ProView interfaces with traditional PACS networks and digital imaging modalities to transfer images to standard PCs for clinician review.


The pending acquisition of CompuRad by film digitizer manufacturer Lumisys will have a major impact on CompuRad's exhibit at the meeting. If shareholders at Lumisys and CompuRad vote on Nov. 25 to approve the joining of the two companies, CompuRad will exhibit as a second Lumisys booth at the meeting. If the shareholder vote needs to be postponed, CompuRad will exhibit under its own name.

In any event, Tucson-based CompuRad will show the iArchive package it acquired from Star Technologies (PNN 9/97) in conjunction with a DLT jukebox from StorageTek. The company will also show new software releases for its iView Pro Windows NT-based viewing software package and its ClinicalWare Web-based image and information management software.

DeJarnette Research Systems

DeJarnette of Towson, MD, will emphasize its new line of PACS workstations. Called VisiShare, the workstations are available in configurations ranging from low-end teleradiology computers up to 2K x 2.5K diagnostic workstations. VisiShare workstations are based on Windows operating systems, with high-end systems running Windows NT and low-end systems using Windows 95. Also on display will be a second-generation ImageShare quality-assurance station for computed radiography and the company's MediShare medical informatics gateway between HL-7 and DICOM.

DR Systems

San Diego-based DR Systems will highlight Universal Manager, a new image acquisition system that enables clinicians to use a single DR Systems workstation for functions that previously required multiple computers. In new archiving developments, the vendor will show a 600-platter CD-ROM archiving jukebox.

Dynamic Healthcare Technologies

The HIS vendor will introduce a teleradiology component to its PACsPlus+ offering. The component, called WebSight, is based on Web protocols and will enable both sending and receiving of images, according to the Maitland, FL-based vendor. The company will also showcase PACsPlus+ release 2.0, which adds some elements to the product that are typically found in radiology information systems (PNN 10/97), according to the firm.

Eastman Kodak

A highlight of the Kodak booth this year will be the company's new line of Windows NT-based workstations (see story, page 3). Kodak, of Rochester, NY, will also discuss its recently completed PACS installation at New York Hospital in New York City; in addition, this RSNA meeting will be the first since the company bought the Nova MicroSonics ultrasound miniPACS business from ATL in April.

Look for Kodak to debut the Digital Science 9000D dry printer as a work-in-progress. As of press time, Kodak declined to reveal whether the system was a laser or non-laser printer.

Kodak will also discuss its Kodak imaging network services initiative, a program designed to help healthcare facilities improve the performance and reliability of their networked imaging equipment. The program provides consulting and planning, and network assessment, design, and implementation services.


Multimodality vendor Elscint will highlight Interview, its name for the MediSurf Web-based image distribution software product developed by fellow Israeli vendor Algotec Systems (PNN 9/97). Employing applets based on Sun's Java programming language, Interview allows referring physicians with the proper security clearances to access patient images and data from a central server on the Internet, LAN, or WAN, according to the companies.


In addition to showcasing its new PACS Pro/DX line of Windows NT-based workstations (PNN 6/97), EMED of San Antonio, TX, will continue to offer at no charge its MultiView teleradiology software package. The vendor will also show the new MultiView 3.0 software release (PNN 10/97), as well as features, called extensions, that add functionality to the basic MultiView package. EMED has added extensions supporting wavelet compression algorithms and DICOM remote query-retrieve.
