A method, system and device for performing measurement and classification for CT-FFR, and a storage medium, for dividing lesions into different types according to a Coronary Computed Tomography Angiography (CCTA) image, determining focus lengths of lesion positions according to different lesion types, then determining Computed Tomography Fractional Flow Reserve measurement ranges according to the focus lengths of different lesion types, establishing statistical matrices to subject all Computed Tomography Fractional Flow Reserve (CT-FFR) values within the measurement ranges to calculation, and finally subjecting the calculation results to hemodynamical classification. By performing lesion specific classification of lesions in a hemodynamical sense, the accuracy and stability of CT-FFR assessment is enhanced, interference is reduced, and a more reliable solution is provided for clinical physicians and patients.
