ROI Mask

Mask pixels

Outside ROI / Inside ROI

When Inside ROI is selected, the pixels inside the ROI are masked. The pixels outside the ROI are left unchanged.

Masked pixels' value

The value to replace the masked pixels with.

Scope

Current image / All Active Images

Mask the pixels only in the current image of the active image window. For single dimensional, the All active images option will mask all images. For multi-dimensional series the All active images option will mask all images for the currently active series (as shown in the Scroll: drop-down box). The other series will not be masked.

Create binary mask from ROI

When this option is checked, the non-cleared pixels are all set to 1, thereby creating a binary mask. (i.e. one inside the ROI and zero outside).

Note: The ROI Mask dialog box is displayed when you select ROI -> ROI Mask ... from the Measure menu
