Abstract

The invention discloses a white matter fiber bundle tracking method, which comprises the following steps of: establishing a white matter fiber bundle tracking mathematical model, inputting an initial voxel of any white matter fiber bundle needing to be tracked, and outputting a final white matter fiber bundle tracking result according to the established mathematical model. According to the white matter fiber bundle tracking method, the pre-trained model is used for processing data collected in a few magnetic resonance gradient directions, and a good fiber bundle tracking effect is obtained.

Description

technical field [0001] The invention relates to a data processing method, in particular to a method for tracking white matter fiber tracts. Background technique [0002] Magnetic resonance-based diffusion tensor imaging (Diffusion Tensor Imaging) technology detects the diffusion signal of the brain voxel by scanning a series of magnetic resonance gradient (Gx, Gy, Gz) field strength vectors, so as to obtain the diffusion signal in (x, y) ,z) The distribution of vector angle directions, so as to calculate the growth direction of white matter voxels for tracking. In order to obtain a good tracking effect, more gradient directions need to be collected. For fine fiber tract tracking, more than 60 gradient directions need to be measured, which greatly increases the scanning time, not only requires the patient to have a high degree of obedience to endure long-term scanning, but also greatly increases the time cost of the scanning machine. Existing MRI clinics generally only carr...
