Abstract
A system (100) for determining flow parameters of a lumen (110) in a hyperemic state induced subsequent to a contrast agent injection (Inj 1) into the lumen in a basal state, is provided. The system comprising one or more processors (120) configured to: determine (S110), based on received angiographic data representing the injected contrast agent and/or received injector data representing the injected contrast agent, a temporal window (TH0, TH1) representing a duration of the induced hyperemic state; and output (S120) a signal (Sh) indicative of the temporal window (TH0, TH1).
Claims15
A system for determining flow parameters of a lumen, the system comprising:
- one or more processors configured to:
- receive angiographic data representing at least one of contrast agent injected into the lumen in a basal state and injector data representing the injected contrast agent;
- determine, based on the received angiographic data, a temporal window representing a duration of an induced hyperemic state subsequent to injection of the contrast agent into the lumen;
- and
- output a signal indicative of the temporal window.
