Abstract:
In a correction method and apparatus for a magnetic resonance diffusion weighted imaging image, a diffusion weighted imaging image is corrected based on a launch site correction factor and/or a receiving field correction factor. The launch site correction factor is used for correcting inhomogeneity of a launch site, and the receiving field correction factor is used for correcting inhomogeneity of a receiving field. The imaging sequence of the diffusion weighted imaging image is thereby improved and the corresponding image reconstruction of the diffusion weighted imaging image, and the homogeneity of the diffusion weighted imaging image also can be improved, without measuring the intensity of the launch site, which significantly reduces the correction workload and is easy to automate.

Claim (Index 6):
The correction method as claimed in  claim 5 , wherein in that the preset relationship is that, for the same diffusion sensitive factor, the excitation pulse flip angle setting value of the second diffusion weighted imaging image scanning is N times the excitation pulse flip angle setting value of the first diffusion weighted imaging image scanning, where N is a positive number, the excitation pulse flip angle actual value \u03b1 actual  of the first diffusion weighted imaging image scanning is determined according to a first general formula, and the first general formula is Sin \ue8a0 ( N * \u03b1 actual ) Sin \ue89e \ue89e \u03b1 actual = S 2 , measured S 1 , measured , wherein S 1,measured  denotes the image signal intensity of the first diffusion weighted imaging image scanning, and S 2,measured  denotes the image signal intensity of the second diffusion weighted imaging image scanning.
