12 Reconstructed Image Orientation
The patient position information stored in the image header correctly reflects the orientation
(RAS) information for the patient. Viewing applications will correctly reflect Right (R), Left (L),
Anterior (A) and Posterior (P) of the patient.
The reconstructed image orientation may differ from preferred anatomical viewing presentation
in which the patient's Right is on the viewers Left and patient's Left is on the viewers Right. For
example, when the patient is scanned Head First and Prone the patients's Left is on the
viewer's Left and the patient's Right is on the viewer's Right. The image presentation will need
to be modified to display preferred anatomical viewing. Some viewing stations may not have the
capability to flip the image presentation, but if the capability exists, you must use display tools
such as Flip to change the presentation of the image.
Some remote viewing stations may have the capability to set default viewing protocols. This is
another tool that can be used to set an anatomical viewing presentation.
Post processing applications automatically orient images in anatomical viewing orientation.
These applications create axial images in anatomical viewing presentation. Please see Display
Applications for more information. The system also provides the capability to create Gray Scale
Presentation State Objects (GSPS) to flip the image orientation.
Chapter 3 Safety
CAUTION
GE CT image reconstruction is in an orientation viewing from the patient's feet.
The reconstructed orientation is the orientation the image is installed in the image
data base and is the orientation images are networked with to a remote viewing
station.

How do I clear Ge Revolution collision sensor
To clear the collision sensor on a GE Revolution CT, remove any obstructions detected by the sensors located beneath the front and back of the table. Once the area is clear, you can continue positioning the table.
