The present invention can locate and evaluate precisely different disease focuses for cerebral vascular diseases and determine the disease focus sizes and spatial anatomic relations of disease focuses, and has important application value in medicine. Automatic method based on absolute quantizing theory with fast operation speed may be adopted. The method has high credibility, applicability and accuracy.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a digital method for magnetic resonance perfusion imaging. The invention relates to information processing technology and magnetic resonance imaging technology. The invention utilizes the principle of magnetic resonance and statistical theory to realize a method for locating and extracting lesion areas in brain function images. Background technique [0002] Prior art The magnetic resonance imaging (magnetic resonance imaging, MRI) technology originated in the 1970s, and has been widely used in the fields of medicine, geology, biology and the like after only 30 years of development. In the medical field, the advantages of MRI mainly include: (1) The imaging process is non-invasive, non-destructive, and free of electromagnetic radiation to the human body. (2) MRI can choose different parameters such as proton density, T1 and T2 imaging. Compared with X-CT, these imagi...
