   We were able to detect acute ischemic stroke at its early stage by using Iterative Reconstruction in X-ray CT to apply Forward projected model-based Iterative Reconstruction Solution imaging to a phantom. CNRLO exceeding FBP was FIRST Brain LCD of standard and strong, and Considering the FOM, approximately 400 and 600 mA is good. FIRST in CT images could be used clinically to judge whether thrombolytic therapy with the use of rt-PA is applicable to acute-stage cerebral infarction. Therefore, optimal conditions for visualizing acute-stage cerebral infarction were achievable.
