Abstract
The present disclosure provides a method for correcting a resting blood flow velocity on the basis of an interval time between angiogram images, comprising: acquiring, in an angiography state, an average blood flow velocity Vfrom a coronary artery inlet to a distal end of a coronary artery stenosis (S); acquiring a time difference Δt between start times of two adjacent bolus injections of contrast agent (S); obtaining a correction coefficient K according to the time difference Δt (S); obtaining a resting blood flow velocity Vaccording to the correction coefficient K and the average blood flow velocity V(S), as well as an apparatus configured for implementing the above method. The disclosure obtains the resting blood flow velocity Vaccording to the correction coefficient K and the average blood flow velocity V.
