Spin-polarized gas e.g. helium, magnetic field wide-range homogenizing method for e.g. magnetic resonance tomography, involves forming cylinder barrel such that same magnetic field strength prevails in barrel as in inner space of cylinder
The method involves magnetizing a field-forming cylinder barrel (2) parallel and similar to a field vector, where the cylinder barrel is made of a magnetically soft, ferromagnetic material. The cylinder barrel is formed in such a manner that a same magnetic field strength (H) prevails in the cylinder barrel as in an enclosed inner space (15) of a cylinder. A magnetic flux density is facilitated in the cylinder barrel and the cylinder barrel thickness is adapted continuously to the magnetic leakage flux of the cylinder barrel along a barrel height. Independent claims are also included for the following: (1) a device for producing a wide-range homogenized magnetic field in an enclosed inner space of a cylinder (2) a transport and storage device for a spin-polarized gas (3) a device for imaging or spectroscopic magnetic resonance with a magnet and magnetic field.
