Description

technical field

[0001] The invention belongs to the technical field of nuclear magnetic resonance imaging, and in particular relates to magnetic resonance spectrometer technology, in particular to a measurement method, device, computer equipment and non-uniform field magnetic resonance system for the decay time constant of a transverse magnetization vector. Background technique

[0002] Nuclear magnetic resonance technology is a technique that uses the nuclear magnetic resonance phenomenon of hydrogen protons to image or detect the composition and structure of substances. Nuclei containing a single number of protons in the human body, such as the hydrogen nucleus, have a spin motion for the protons. The spin motion of charged atomic nuclei is physically similar to individual small magnets, and the directionality distribution of these small magnets is random in the absence of external conditions. When the human body is placed in an external magnetic field, these small magnet...
