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
Reducing the magnification level
Restoring the original level of magnification
Magnifying regions within images
Figure 19. Magnification dialog box options
Tip: To review or compare a magnified region of the image with the same region at its original magnification, press Shift. To return to the Magnified view, release the key.
Figure 20. The larger size magnifying glass such as shown in B and C allows to inspect a larger region of the image
Showing intensity values through the magnification glass
Improving contrast, adding color, etc.
lookup table (LUT)- maps the frequency distribution in a histogram to pseudo-color values.
