Model: Simplified Reference Tissue Model

Description

This is the SRTM model itself by which predicted values are generated.

Usage

srtm_model(t_tac, reftac, R1, k2, bp)

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.

reftac

Numeric vector of radioactivity concentrations in the reference tissue for each frame.

R1

Parameter value for R1

k2

Parameter value for k2

bp

Parameter value for bp

Value

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