BREAKING THE SILENT
TECHNOLOGY BARRIER.
Historically, most attempts at reducing MR noise have focused on muffling or
dampening the sound by adding insulation inside the MR system, modifying
internal structural supports to change the natural mechanical frequency or
reducing the gradient slew-rate to minimize the induced mechanical vibration.
All of these methods, however, have failed to reduce noise significantly enough
to really change the patient experience.
High Fidelity Power Electronics
Our High Fidelity Power Electronics platform
helps maintain the extremely stable gradients
and radio frequency (RF) required to avoid
generating image artifacts during reconstruction.
Ultra-fast RF switching capabilities
Since Silent Scan technology avoids switching
gradients rapidly, it’s crucial that the RF coil
system be capable of switching from transmit to
receive mode within microseconds to maximize
signal-to-noise ratios within the images. And the
GEM Suite of coils is designed to do just that.
Our Silent Scan technology utilizes a different approach by eliminating the noise
at the source. Since noise from an MR scanner is generated through an interaction
between the MR magnetic field and the imaging gradients turning on and off,
we developed three unique, breakthrough technologies that revolutionize how
MR images are acquired. The result is the image quality you would expect from
a conventional MR scan, with a fraction of the acoustic noise.
