Cathode Ray Tube
A substance for producing low temperatures. Liquid helium is the cryogen used to cool the
magnet to approximately 4 Kelvin (269 C or 452 F).
An apparatus maintaining a very low constant temperature. The cryostat consists of one
CRYOSTAT

concentric, cylindrical container housed in an outer vacuum tight vessel. The magnet and
shim coils are mounted in the inner container. The container is filled with liquid helium. The
shields surrounding the inner container are kept cold by a refrigeration device.

Digital Signal Processing
Area where the magnetic flux density is greater than five gauss. Personnel with cardiac
pacemakers, neurostimulators and other biostimulation devices must NOT enter this zone.
EXCLUSION ZONE

Signs are posted outside the five gauss line alerting personnel of this requirement. Since the
magnetic field is threedimensional, signs are also posted on floors above and below the
Magnet Room in which the five gauss line exists.

1

A unit of magnetic flux density. The earths magnetic field strength is approximately one half
GAUSS (G)

gauss to one gauss depending on location. The internationally accepted unit is the tesla (1
Tesla = 10,000G and 1 milli Tesla =10G).
GP

Gradient Processor [Board]
The amount and direction of the rate of change in space of the magnetic field strength. In
GRADIENT

the magnetic resonance system, gradient amplifiers and coils are used to vary the magnetic
field strength in the x, y, and z planes.

Uniformity. The homogeneity of the static magnetic field is an important quality of the
magnet.
Image Compute Node.
A component with an internal operating system (similar to a PC)
used for Image reconstruction in the VRE.
Contains hard drives and an operating system
Installation Calibration Wizard.
This wizard is available in two different modes: Install and

Upgrades.
It can be found in the proprietary Common Service Desktop under the

Maintenance mode is available after all calibrations and tasks in the
install mode are complete.
