MR Scanning
Once the Luminant
proceed with scanning.
Note
Make sure that the entire localizer frame is positioned within the
confines of the scanner head coil.
Note
While exact orientation is not necessary, use a towel or head rest
beneath the superior part of the localizer to align it so that the
UCHRA is perpendicular to the central axis of the scanner head
coil.
Note
The UCHRA intubation hoop must be in the down position to fit
into the MR scanner head coil.
Caution Always keep patient movement to a minimum during
the MR scan.
CT Scanning
Once the Luminant
proceed with scanning.
A Radionics CT clamping plate attaches the UCHRA assembly to the
CT couch and aligns the Luminant
the scanner.
Caution Always keep patient movement to a minimum during
the CT scan.
Note
To optimize automatic localization when selecting rods on CT
images, Rod Threshold and Window Level settings should be
adjusted. Rod thresholds between 1200 and 1500 are normally
sufficient to allow selection of the rod centers. Window Level
settings should be adjusted so that the rods appear clearly as
rings, distinct from the other localizer components.
Rod Orientations
Confirm correct localizer placement by verifying accurate rod orienta-
tions while the patient is scanned.
