Summary[edit]
| Description |
English: Further manipulation of the magnetic dipoles in a given volume can be accomplished by varying the static magnetic field exerted on the protons. As shown in the graphic by the green arrows of increasing size, the magnitude of the magnetic field experienced by these protons increases as you go up the Y-axis. Since a greater magnetic field will exert a greater force on the protons, they will precess faster. This fact is used in many interesting ways, a few of which will be covered in this tutorial. The general idea is that many problems can be overcome by changing the Larmor frequency of groups of protons by varying the magnetic field in a given direction. |
