4. Set the HEAD and FOOT positions with the tube stand at approximately the midpoint of what will be
the tube travel (typically
knee height
of the patient) using the laser light/tube angle method.
5. Set the HEAD center point, using the laser light, slightly HIGHER than normal (i.e., 5cm—or 2 in—
above the top of the anatomy you intend to acquire—e.g. iliac crest).
6. Set the FOOT center point as low as possible to intersect just below the ankle joint.
7. Press [SET].
If you receive an error after pressing [SET], reposition the patient, check the accuracy of the COI,
and repeat steps 4-7.
Complete setup and acquisition as described in

Image Viewer
Each acquired image is a “sub-image.” After the sub-images are processed, the system aligns and pastes
the sub-images into a single “composite” image. The pasted composite is one long image that has con-
tinuous anatomical content with the same processing applied throughout.
The following images are stored for the exam and are available for viewing:
The acquired raw sub-images in the “RAW” series (2–8 images, depending on the protocol and the
size of the coverage area)
The processed sub-images in the “PROC” series (1 processed image for each raw image)
1 processed pasted composite image in the “PROC” series (no “raw” pasted composite images are
displayed or stored)
Any re-processed sub-images or re-pasted sub-images and pasted composite images in the “PROC”
series
All image zoom, annotation, adjustment tools (brightness, contrast, windowing, rotation, etc.), and re-pro-
cessing are available for the pasted composite image and the sub-images. The controls function the
same as for non-pasting acquisitions. Refer to
for more information about
image adjustment.
The pasted composite image is treated as one image entirely. Image adjustments are applied equally to
the entire pasted composite image.
DEI is not shown for derived images. This includes Dual Energy subtraction images (soft tissue and bone)
and pasted composite images.
