Model: Two Tissue Compartment Model with Irreversible Trapping

Description

This is the Two Tissue Compartment Model with Irreversible Trapping model itself by which predicted values are generated.

Usage

twotcm1k_model(t_tac, input, K1, k2, k3, k4, Kb, vB)

Arguments

t_tac

Numeric vector of times for each frame in minutes. We use the time halfway through the frame as well as a zero.

input

Data frame containing the blood, plasma, and parent fraction concentrations over time. This can be generated using the blood_interp function.

K1

Parameter value for K1

k2

Parameter value for k2

k3

Parameter value for k3

k4

Parameter value for k4

Kb

Parameter value for Kb

vB

Parameter value for vB

Value

A numeric vector of the predicted values of the TAC in the target region.
