Next/Previous Time Point


These two icons move to the next or previous time point.

To copy and paste to individual images, use the copy/paste zoom in the edit menu.

Automatic Window Levels

Atumaticall adjust window level.jpg

This turns on automatic window levels, so the window levels are adjusted for each slice as you move through the volume based on the recommended window levels written in the DICOM header (DICOM only). For all other image types, when the button is pressed, the window levels are automatically adjusted for the current slice, but they are not readjusted as you move from slice to slice. Manually adjusting the window levels turns off the automatic settings for DICOM images. To reactivate the automatic settings, hit the button again.

Color Map

Apply pseudo color map.jpg

This command assists in coloring the image by giving red for the highest intensity and blue or purple for the lowest intensity. First, select the image to which you want to add colors, then click on the "apply pseudo color map" icon which will create the image with colors according to the scale on the right of the image (red is the highest intensity, green is medium intensity and blue is the lowest intensity).
