Feng model for fitting of arterial input functions

Description

This is the model itself for the Feng model of the AIF.

Usage

Arguments

time	Time of each sample.
t0	The delay time. This is the point at which the linear rise begins.
A	The multiplier of the first exponential.
alpha	The rate of the first exponential.
B	The multiplier of the second exponential.
beta	The rate of the second exponential.
C	The multiplier of the third exponential.
gamma	The rate of the third exponential.

Value

Model predictions

Examples

blmod_feng_model(1:1000, 30, 7, 0.02, 2, 0.005, 4.5, 0.0005)
