Positioning the Patient
Patient Positioning For CT Scans - At A Glance
Position the patient for minimal movement and maximum image quality. To prevent patient
movement:
•
When possible, use the head support, strap and chin cup.
•
Stabilize patient’s feet with a foot stool if needed.
•
If shoulder clearance is a concern, lower the chair elevation and tilt chin up.
•
Do a Dry Run to test for shoulder clearance.
1. Adjust chair height.
Chair seat is typically
in top slot. Set
elevation with
horizontal laser light
at patient’s smile line.
2. Close the gate.
3. Ensure the patient’s
chin is sitting
comfortably yet firmly
in the chin cup.
4. Secure patient in
head support and
attach head strap
around forehead.
5. Adjust tilt of jaw.
Occlusal plane
should be horizontal.
External reference:
tragus-ala line
horizontal.
•
Do not swallow during the scan.
•
Slow shallow breaths during the
scan.
•
Close eyes during the scan.
•
Stay as still as possible.
Instruct Patient Prior to Scan
If Gate won’t close:
•
Use the head support/strap
without the chin cup. Keep gate
open and remove metal chin
support mechanism.
OR
•
Take out head support and use
just the chin cup.
OR
•
Slide patient slightly forward
allowing room to lean back into
scanner with chair in upper slots.
For Orthodontics:
•
Use just head support/strap so
the chin cup is not visible.
Remove metal chin support
mechanism.
