The invention relates to the technical field of medical
image detection, in particular to a medical
image analysis method and
system based on
image processing, and the method comprises the following steps: collecting a
diffusion tensor image, carrying out the filtering preprocessing, normalizing the main
diffusion direction, extracting an energy super-threshold
voxel, calculating the node distance offset, and carrying out the
correlation analysis to generate an atlas. And interpolating and aligning the brain return boundary to obtain a
coupling graph, and outputting an abnormal probability distribution graph in a classified manner. According to the method,
fiber details are ensured by adopting
anisotropic diffusion filtering
noise reduction of a
diffusion tensor image sequence, three-dimensional normalization and
wavelet energy analysis are coordinated, node detection specificity is enhanced by dynamic threshold screening, space-time
coupling is quantified by combining displacement
Euclidean distance and
time sequence relevance, and an individualized
coupling model is established by interpolating and fusing brain return boundaries; the template rigid constraint is broken through, the
support vector machine recognizes an abnormal mode, structural
distortion and
functional abnormality cross-scale detection is achieved, and the early
lesion image marker recognition efficiency is improved.
