Use the F12 key to toggle the localizer lines on and off.
Use the Alt-F12 key to toggle hash marks on and off for all image frames.
The hash mark settings page defines the parameters the viewer uses to calculate spacing limits for hash marks and other positioning features. You can define the distance that defines intersecting image planes and when the Magic X positioning tool is out of range. This setting page also sets the defaults for which kind of hash marks to display. To display the hash mark settings page, go to Settings/Customize Settings/Hash Marks.
eRAD PACS makes a distinction between hash marks and localizer lines. A localizer line is a graphic that shows the intersection of one image on another. This setting applies to the selected image and results in a single line on the intersecting images. Hash marks are the collection of multiple localizer lines. This setting applies to all the series of images in the selected frame. The result is one or more lines drawn on the intersecting images, with the displayed image (in the stack frame) showing a bold line.
Hash marks can be displayed in all or individual image frames.
Click on Settings/Localizers/Show Localizer Lines on Select Image to display a localizer line in a single frame.
Click on show localizer lines on all images to display localizer lines on all image frames.
Select show hashmarks on select image, or show hashmarks on all images. When a setting is enabled, a checkmark appears next to the menu label.
Note: By default, hash marks only appear on an image if it is marked as a localizer image, or if eRAD PACS concludes it is an unmarked localizer. Hash marks only appear if images are spatially related, i.e., the image objects are labeled with the same frame of reference.
