GE Healthcare Optima MR450w 1.5T - Manual (Page 7)

“
Under that sleek exterior is some of the most versatile technology
we’ve ever built into an MR. Our goal has been to deliver a 1.5T
system with a 70 cm bore with no compromises. In fact, the
Optima MR450w is engineered to be 30 percent lighter than
our previous systems without sacrificing performance.

Acoustic Reduction Technology (ART)
The right MR experience goes beyond bore size and positioning.
Patients today are also asking for a quiet MR exam. Acoustic Reduction
Technology (ART) delivers just that, reducing acoustic noise. ART is such
a practical application, it will become an essential part of your brain,
spine and MSK scans. And because ART reduces noise by optimizing the
gradient performance, there’s virtually no compromise in image quality.
