Hitachi Medical Systems America Releasing Ascent(TM) 5.0 Operating System for Altaire(R) and AIRIS(R) II.

TWINSBURG, Ohio -- The Ascent 5.0 software upgrade program for Hitachi's Altaire and AIRIS II customers is scheduled to begin in August 2006. This latest version of Ascent, the operating system software for Altaire, AIRIS II, and AIRIS Elite Open MR systems, will provide benefits in the areas of image quality, workflow and clinical capability.

"As always, upgrades to Ascent are offered at no charge to those customers under warranty or enrolled in our industry-leading Ultra Plus Customer Support Program," noted Shawn Etheridge, HMSA MR Marketing Director. "Hitachi is committed to keeping its customers on the cutting-edge of technology through a schedule of regular software upgrades and enhancements."

In its standard configuration, Ascent 5.0 provides many features for both Altaire and AIRIS II, including sequence enhancements, like Shared Echo FSE for simultaneous collection of high quality PD and T2-weighted images, and Gated IR/FIR, which enables free breathing abdominal T1-weighted imaging. Altaire and AIRIS II users equipped with DWI will also enjoy One-Button Acquisition DWI, which initiates all scans necessary for DWI and ADC images with one interaction. The addition of FatSep[TM] FSE will allow AIRIS II users equipped with Hitachi's FatSep[TM] sequence to expand its application to T2-weighted imaging, combining the throughput advantage of FSE with fat/water separation.

Additional exciting new options for Altaire users include CardioSuite, a powerful cardiac imaging package, as well as RAPID[TM] parallel imaging software and receiver coils.
