Study on Model Iterative Reconstruction Algorithm vs. Filter Back Projection Algorithm for Diagnosis of Acute Cerebral Infarction Using CT Images

Figure 6

Statistical results of CBV of gray and white matter in the brain among patients from groups A and B under the six reconstruction methods. A is the statistical result of gray matter in patients from the two groups under various reconstruction methods; B is the statistical result of white matter in patients from the two groups under different reconstruction methods. The CBV value of patients from group B was different considerably by comparing with group A ( < 0.05).
