| abstract |
An exemplary system, method and computer-accessible medium for determining an arterial input function (AIF) of a mammal(s) can be provided, which can include, for example, receiving information related to a global circulatory system of the mammal(s), and determining the AIF based on the information by modeling a blood flow in the global circulatory system of the mammal(s) in terms of an input response function(s). The input response function(s) can include a delayed input response function(s). In certain exemplary embodiments of the present disclosure, the input response function(s) can include at least three input response functions, and each of the input response functions can be from a different part of a body of the mammal(s). The AIF can be determined by coupling the input response functions. The AIF can be further determined based on a total tracer amount in an organ(s) of the mammal(s). |
