Hitachi .7T Altaire

High-Field Performance With The Comfort Of Open MR

The seamless blending of high-field performance and the patient comfort of Open MRI was up until now mutually exclusive. Hitachi .7T Altaire employs a unique blend of innovative Hitachi features called VOSI® technology, optimizing each sub-system’s performance in concert with the other sub-systems. In this way, Altaire is able to shatter old performance barriers while still delivering all of the benefits of Open MRI. Hitachi .7T Altaire is exactly what one would expect from Hitachi, the world leader in Open MRI.


Vertical-Field with Optimized Sub-System Integration

An MR imaging system is made up of sub-systems that must work in close concert to create a high quality magnetic resonance image. Careful specification and design of not only the magnet, but also the gradient, radio frequency and computer sub-systems is critical to consistently high image quality. Optimization of any one of these sub-systems in isolation will not necessarily yield high image quality.

 

VOSI (pronounced Vo' sigh) technology is the embodiment of Hitachi's attention to each aspect of the imaging system's specification, design and manufacture.

Through the application of VOSI technology, Hitachi is able to optimize image quality in an open architecture vertical field system.
