tic_auc

This function returns area under curve from raw time intensity curves using
the trapezoid method. It is recommended that plotresult is set to TRUE in the
first instance to visually confirm the analysis.

Plots and analyzes time-intensity curve data, such as data from
(contrast-enhanced) ultrasound. Values such as peak intensity, time to
peak, area under the curve, wash in rate and wash out rate are calculated.
