Displaying images using the default view
Figure 17. Images open in the default image windows
Displaying images using the lightbox view
click Magnify Region and move the pointer to the image section to be magnified. Click Default Mode when finished.
Double-clicking an image in the lightbox view updates the 2D image frame for that image.
Displaying images using the cine view
Adjusting magnification
Changing the magnification level
This section explains how to change the magnification level of the image using the icons on the Image toolbar in the MIPAV window.
To learn how to adjust the magnification level using the Image toolbar, refer to
To learn how to set the magnification level using the other methods, see volume 1 of the MIPAV User's Guide.
Magnifying images
