In mathesong/kinfitr: Kinetic Modelling of PET Time Activity Curves

Convolved Feng model for fitting of arterial input functions

Description

This is the model itself for the Fengconv model of the AIF with an extended injection.

Usage

blmod_fengconv_model(time, t0, A, alpha, B, beta, C, gamma, ti)

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.
ti	The infusion time of the bolus.

Value

Model predictions

Examples

blmod_fengconv_model(1:1000, 30, 220, 0.4, 100, 0.05, 22, 0.003, 30)
