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

Figure 3

Statistical results of SD values of gray and white matter in the brain among patients from groups A and B by different reconstruction methods. A and B are the statistical results of gray and white matter in patients from the two groups under various reconstruction methods, respectively. The SD value of patients from group B was different greatly in contrast to group A ( < 0.05).
