BLOOD FLOW DYNAMIC ANALYSIS DEVICE, X-RAY CT SYSTEM, MRI SYSTEM, AND BLOOD FLOW DYNAMIC ANALYSIS PROGRAM

摘要

PPROBLEM TO BE SOLVED: To increase the quantitative precision by removing affections of a delay or a dispersion without increasing labor or burden of an operator in a blood flow dynamic analysis. PSOLUTION: An artery inputting function and a time-density curve in each noted pixel are determined from a tomographic image which is photographed by a medical image photographing device (S401 to 407). For each noted image element, a correction parameter for correcting a slippage in blood flow reaching time or a dullness in the shape of the time-density curve is calculated (S408). From the correction parameter, the artery inputting function is corrected for each noted image element (S409). A transmission function is determined from the artery inputting function and the time-density curve for each attention pixel after the correction (S410), and living body functional information is formed (S412).
