Sony debuts Professional Disc archiving solution

Sony Electronics disclosed its new Professional Disc to enhance the industry's archiving methods. The storage device is intended for data optical storage drives, automated devices and media to OEMs and system integrators.

 Based on blue laser technology, the Professional Disc stores up to 23 gigabytes (GB) of native capacity per rewritable or write-once/ready-many (WORM) disc, while the drive sustains a maximum transfer rate of 11 megabytes (MB) per second.

 "Traditionally when people needed a backup or archive, they did it on a tape disk, but this new technology that we are showcasing is suitable for any image intensive acquisition, including CT, MRI and digital mammography," explains Mark Wagner, Manager Medical-IT Solutions. "There are many different places it can be used; it just depends on the workflow."

 In the future, the company anticipates a second-generation drive and media to the market by 2005 that will feature up to 50 GB of capacity with a transfer rate of 22MB/sec, eventually followed by a third generation of drive and media featuring 100 GB of capacity with a transfer rate of 43 MB/sec.

 In addition to its already released FilmStation dry film imager, Sony Electronics also brought its new A6 color video medical-grade printer with a USB 2.0 high speed interface intended for ultrasound and endoscopy.

 The UP-D23MD printer produces 400dpi prints with more that 16 million color tones. In addition to connecting directly to modalities, the device can print images from a PC or network server. The company says the printer is priced at $2,379.

 First introduced at RSNA 2002, Sony's FilmStation delivers high resolution images in 4,096 shades of gray for a full range of modalities, including CT, MRI, CR, DR and ultrasound. Compact in design with the ability to be positioned on its side, the FilmStation can print up to 70 14-by-17-inch films per hour.

 
2 new storage devices debut at TDK

 Both systems offer connectivity to a DICOM-compliant network, accept a range of DICOM-compliant information object definitions (IODs) and offer easy management and navigation of single or multiple patient studies.

 While both systems are similar in operation and functionality, the CDRS-1100AUTO TP also features a Rimage Amigo II automated CD production station which mass-produces on-demand CD-R discs and automatically prints patient and institute on information on the label.

 
TeraMedica unveils cost-effective image storage

TeraMedica, a medical informatics company in Milwaukee, Wis., showcased its Intelligent Image Manager (TI²m) software version 2.0 recently purchased by the Mayo Clinic in Rochester, Minn.

 "TeraMedica provides software that works on any Unix server platform, and operates on any storage hardware that the facility uses," said Paul Schmelzer, executive vice president and COO.

 TI²m is designed to capture data from imaging devices or PACS, store the digital images, and make them available for delivery to the point of patient care across the healthcare enterprise. The data is "migrated" from the conventional methods of storage today and moved to an environment that handles it in a cost effective manner.

 "Medical imaging is fast approaching a petabyte scale data management problem with a terabyte architecture purchased at gigabyte prices," explains Schmelzer. "The software allows images to be taken from the devices and stored on-line and off-line dependent on their retrieval characteristics.

 "In relation to PACS, we take the image data from the PACS, off load it and get it into the mass scale storage units that vendors produce. From that central repository, the data can be served electronically to on call physicians or it can be tied into a comprehensive medical record (EMR)," added Schmelzer. "In a conventional world, all that's tied up in the PACS and it becomes a departmental problem.

 
Viatronix adds new dimension to vascular imaging

Viatronix Inc., provider of 2D and 3D visualization software, highlighted its recently FDA-approved V3D-Vascular module designed specifically to ease the burden placed on radiologists and technologists to create clear visualization of complex vascular anatomy. The module allows the user to examine vessels in 2D and 3D, fly through, view hard and soft plaque and make precise measurements. Viatronix also hallmarked its V3D- Colon system that renders 2D computed tomography images of the colon into 3D images to screen for polyps and other abnormalities. At RSNA 2003, researchers revealed in a study that virtual colonoscopy is as sensitive as and less invasive than conventional colonoscopy in screening average-risk patients.
