[0076] Step 1: Create a sample database. Collect multi-TI and multi-TE T1 and T2 weighted imaging image data of multiple (for example, 50) standard individuals, and establish a sample database of magnetic resonance characteristic attributes, including relaxation time of samples, characteristic constants, and binary images of sample tissue segmentation Contrast-optimized signal-intensity-weighted images (ie, scout images) of samples and samples. Calculation of relaxation time T1 and T2 is obtained by fitting with the following formula:
[0077] S(TI)=a+b·exp(-TI / T1)
[0078] S(TE)=c·exp(-TE / T2)
[0079] Where S is the acquired T1 or T2 weighted image signal, and a, b, c are system constants.
[0080] Step 2: Input the target data (that is, the magnetic resonance data that needs to optimize the image contrast, or recommend individualized optimization of imaging parameters), including weighted signal intensity images and imaging parameters.
[0081] Step 3: Register the targe...
