ABSTRACT:
A magnet temperature control device, for use in a magnetic resonance system having a magnet, includes a pipeline and a temperature regulator. The pipeline is connected to a liquid or gas circulation, and the temperature regulator is connected in series in the pipeline to regulate the temperature of the liquid or gas. A part of the pipeline is arranged inside the magnet, while the rest of the pipeline is arranged outside said magnet; the part of said pipeline which is arranged inside said magnet is distributed uniformly within the magnet, and its cross-sectional shape is in an annular, helical, radicalized or network form, or a combination thereof. Compared to the use of a heater that is distributed only on the surface of the magnet, the pipeline distributed inside the magnet can control the magnet temperature more directly and effectively, so as to smooth and eliminate the temperature change of the magnet promptly by the liquid or gas flow therein, thereby making the magnet temperature more stable.
