Embodiment Construction

[0076] In the following description of different embodiments of the invention, functionally identical elements have the same reference numerals, even if they differ in design or shape.

[0077] figure 1 The magnetic field probe 1 shown has a capsule 3 made of a material 19 hardened by UV light. Capsule 3 is spherical. The capsule 3 is solid and closed to the outside. The surface 25 forms a closed surface, and the terminals 35 and 37 for the first coil 7 and the second coil 9 embedded in the capsule 3 protrude from the capsule 3 at only four points. A cavity 11 is formed in the center of the capsule 3, which is completely filled with the MR active substance 5, which in the embodiment described here consists essentially of water, which is doped with a substance that renders the MR active substance 5 The magnetic susceptibility of the capsule 3 is equal to that of the material 19 of the capsule 3 and the magnetic susceptibility of the first coil 7 and the second coil 9 made of...

Abstract

The invention relates to a magnetic field probe (1) having a capsule (3) in which an MR active substance (5) is encapsulated. In particular, two coils (7, 9) are arranged in the capsule (3). Advantageous manufacturing methods for the magnetic field probe (1) and useful uses and methods of the magnetic field probe (1) according to the invention are also described, in which such a magnetic field probe (1) and an arrangement of magnetic field probes (1) are used.

Description

technical field [0001] The invention relates to a magnetic field probe having a capsule in which an MR active substance is encapsulated and a first coil is provided. [0002] The invention also relates to an arrangement system for magnetic field probes. [0003] The invention also relates to methods for producing a magnetic field probe, for measuring magnetic field properties by means of a magnetic field probe, and for operating a magnetic field probe. Background technique [0004] Magnetic field probes having the features described at the outset, arrangements for such magnetic field probes, the production of magnetic field probes and methods for using magnetic field probes are known in practice. [0005] For example, a magnetic field probe with the described features is used to measure magnetic fields generated in MR (magnetic resonance) equipment. Precise data regarding the magnetic field actually applied in the MR measurement range can thus be determined, which data can...
