One device and method opinion system, the Perfused vessel radiography of name, quantitative analysis and visualization for the blood flow parameter from DSA images are provided. Use the bolus rail method of the deconvolution based on the time-density curve connected in a pixel, parameter, including cerebral blood flow (CBF) (CBF) and cerebral blood volume (CBV), average transmission time (MTT), time to peak value (TTP) and Tmax, calculated. The individual reduced concentration curve Chong Die with container can be marked by changeable γ accessories. The parameter of extraction is respectively transformed into the PARAMETER DRAFTING of target, can be indicated with color in the case where different color expression parameter value within the scope of a particular set. The expert opinion and situation diagnosis that PARAMETER DRAFTING with corresponding DSA images abreast allows to assess.
