Embodiment Construction
[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0031] Such as figure 1 Shown is a flowchart of the neuroimaging method of the present invention, which includes the following steps:
[0032] Step S110: Determine the sampling plan and select multiple directions evenly distributed on the unit sphere (such as Figure 4 Among them, 12, 42, 162, 642, etc.), in each voxel, the attenuation of signal strength in these directions is measured using existing technology. Such as magnetic resonance imaging (MRI).
[0033] Step S120: Calculate the dispersion coefficient D in each direction according to the signal attenuation strength obtained in step (1),
