The present invention is related to a method for correcting a diffusion image having an artifact, the method comprising: (a) providing a set of diffusion images comprising the diffusion image having the artifact (b) calculating a first signal intensity of each image in the set of diffusion images (c) plotting a graph of serial number of slice of the set of diffusion images versus the first signal intensity (d) calculating a second signal intensity of the diffusion image having the artifact by performing interpolation on the graph and (e) correcting the diffusion image having the artifact base on the second signal intensity.本發明係關於一種矯正一具有假影之擴散影像的方法,該方法包含:(a)提供一組擴散影像,其包含該具有假影之擴散影像;(b)計算該組擴散影像中每個影像的第一信號強度;(c)繪製該組擴散影像的切片編號相對於該第一信號強度的圖;(d)藉由在該圖上進行內插法來計算該具有假影之擴散影像的第二信號強度;及(e)基於該第二信號強度校正該具有假影之擴散影像。
