NAME
Corrupted data
DESCRIPTION
Incorrectly interpretation or display
REASON
Corrupted data
HELP
Save to a new or different media
An artifact on a MR image can appear when data read off an optical disc became corrupted. There two effects can be seen.
Firstly, Bands where the intensity has been incorrectly interpreted or secondly areas, where the horizontal position of the pixels has been incorrectly displayed. It is important to be able to differentiate between artifacts caused during a MRI scan, from those caused by the associated hardware of an imaging system.

Image Guidance
Review the hardware and store the images on a new disc.

Coupling Constant
 
Spectral lines are split by spin spin coupling into multiplets whose frequencies are separated by an amount depending on the coupling constant, J. The magnitude of J is independent of the strength of the applied magnetic field and is given in units of frequency, Hz.
