lortie.model: Reversible one-tissue compartment 82-rubidium model with flow...

In traceRkinetic: Kinetic analysis for dynamic nuclear imaging: compartmental models

Description

This function implements the one-tissue compartment rubidium-82 model published in [1].

Usage

  lortie.model(input.function, FLV, flow, k2, time.start,
    time.end, a = 0.77, b = 0.63,
    left.ventricle = input.function,
    interpolation.type = 1)

Arguments

input.function	Input function TAC.
FLV	Fraction of blood (from left ventricle) in myocardium TAC.
flow	Myocardial blood flow.
k2	Rate constant.
time.start	Initial acquisition time for each frame (in minutes).
time.end	Final acquisition time for each frame (in minutes).
a	Parameter a of the Renkin-Crone equation implemented in flow2k1. Defaults to 0.77 [unitless].
b	Parameter b of the Renkin-Crone equation implemented in flow2k1. Defaults to 0.63 [ml/min/g].
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.
