Patent ID: 7432708

Claim:
A temperature control method for a magnetic resonance system having a permanent magnet arrangement comprising a first group of magnetic field-generating components and a second group of magnetic field-generating components, said first group of magnetic field-generating components and said second group of magnetic field-generating components, in combination, generating a basic magnetic field of said magnetic resonance system in a region between said first group and said second group, each of said first and second groups having two opposite sides with one of said two opposite sides of each group being closer to said region than the other of said two opposite sides of that group, said method comprising the steps of: stabilizing temperature of said first group of magnetic field-generating components by maintaining respective temperatures at two opposite sides of said first group of magnetic field-generating components constant while maintaining a difference between the respective temperatures at said two opposite sides of said first group of magnetic field-generating components; and stabilizing temperature of said second group of magnetic field-generating components by maintaining respective temperatures at two opposite sides of said second group of magnetic field-generating components constant while maintaining a difference between the respective temperatures at said two opposite sides of said second group of magnetic field-generating components.
