Embodiment 1
[0042] Prognosis prediction clinical detection test of embodiment 1 disturbance of consciousness
[0043] 1) Preprocessing the RS-fMRI data,
[0044] The RS-fMRI data includes slice acquisition time correction, head motion correction, alignment to standard space, spatial smoothing, temporal bandpass filtering, removal of white matter, cerebrospinal fluid average signal, and head motion curve from the data;
[0045] In this method, the brain region segmentation map (such as figure 1 Shown in A) Extract the average time series of different brain regions (or regions of interest, Regionof interest / ROI); this time series reflects the regional average blood oxygen level-dependent signal (such as figure 1 shown on B);
[0046] 2) For the data obtained in step 1), use the "weighted sparse representation" algorithm to optimally calculate the representation relationship between any brain region and other brain region signals, and use the L-1 weighted by the correlation coefficient b...
