irreversible.2c.model: Implements an irreversible two-tissue compartment model

Description Usage Arguments Value

View source: R/models-2compartment.R

Description

This model is basically the same as reversible.2c.model but the parameter k4 is always 0. The simplified equation has been implemented in this function and can be fitterd using irreversible.2c.fit.

  irreversible.2c.model(input.function, K1, k2, k3, vB,
    time.start, time.end, left.ventricle = input.function,
    interpolation.type = 1)

Arguments

input.function

Input function TAC.

K1

K1 parameter.

k2

k2 parameter.

k3

k3 parameter.

vB

Fraction of blood in tissue.

time.start

Initial acquisition time for each frame (in minutes).

time.end

Final acquisition time for each frame (in minutes).

left.ventricle

Left ventricle TAC, used for spill-over corretion. Defaults to input.function.

interpolation.type

Interpolation type selection. Passed to interpolate.tac. Defaults to 1.

Value

The TAC resulting of solving the model with the given parameters.
