Imaging performance is determined by
more than just channels—it’s really
about the shape, size, and number of
elements with the FOV and how they’re
used to form an image. In addition,
precise Radio Frequency (RF) control
is essential to achieving uniform, high
signal-to-noise across the FOV and
ultimately leads to consistently clear
GE Healthcare recently introduced
MultiDrive RF Transmit, ensuring the
RF and amplitude of each pulse are
adapted for the anatomy of interest.
The RF modification produces a
uniform MR signal during reception.
MultiDrive also automatically
compensates and virtually eliminates
B1-induced signal shading across
different body shapes and sizes.
The result is consistently clear
and uniform images.
While digital cameras are often defined
by megapixels, a camera’s ability to
produce clear, undistorted images
relies more heavily on the quality of the
lens and its ability to capture the light.
A poorly designed lens can’t overcome
the best performing camera.
The same holds true in MR. With the
latest surge in wide bore 3.0T systems,
the significance of homogeneity and
its impact on image quality has never
been more important.
No other parameter influences the
quality of fat saturation, anatomical
coverage, and resolution performance
more. If compromises are made to
the magnet field homogeneity, you’re
unlikely to see the benefits of 3.0T wide
bore. That’s why the Discovery MR750w
3.0T magnet supports uncompromised
homogeneity ensuring excellent
resolution across the entire image.
