# Area Under Curve

Class: NodeAreaUnderCurve

Calulate the area under the curve for each voxel in a dynamic series over a set timespan. If a baseline image is connected, values from this image will be subtracted from each voxel before it is added. If no baseline image is connected 0 will be used as baseline.

## Inputs

#### Time Series

Input dynamic series.

Type: Image4DFloat, Required, Single

#### Baseline

Input baseline image.

Type: Image4DFloat, Optional, Single

## Outputs

#### Out

Resulting parameter map.

Type: Image4DFloat

## Settings

#### Timespan(s) Number

The number of seconds the algorithm should use to calculate the area. This value needs to be high enough to include at least two frames.
