In the following we show a plot representing the 0.5 T, 1 T, 1.5 T, and 2 T iso-magnetic
contours at positions accessible to and relevant for the MR worker as far as the static mag-
netic field in the isocenter exceeds any of these values.
⊗
: At this location, the value of the magnetic field B
o
is greatest.
!
The iso-magnetic contour lines are accurate to a value better than 1%. There is very lit-
tle influence from the environment to the scanner. The graphic shows the cover in
nominal position. On a variety of scanners, the position can vary ±5 mm in the axial
direction. The maximum value therefore has a tolerance of ±10%, as small geometric
deviations can cause a significant change in the value.
