CAUTION: The Thyroid Uptake screen is now displayed. Confirm that you have the
correct patient displayed before proceeding.
ATTENTION: L'écran prise thyroïde est maintenant affiché. Confirmez que vous avez le
patient correct affiché avant de continuer
.
7. Select <Count Standard>. The Activity Measurements screen is displayed.
8. Enter the Patient Dose, then select <Accept> to continue. A message is displayed
instructing the user to prepare to count the standard.
9. Position the capsule(s) in the thyroid phantom and set up the collimator for use. Set the
distance on your distance bar and move the collimator into position. A red LED light can be
flipped out from the rim into the center of the collimator face to help align the thyroid
position. Remember to flip the LED back to the retracted position and move the distance
bar to the bottom of the collimator out of the field before counting. Move the distance bar
to the bottom of the collimator out of the field. The capsule count distance and the thyroid
count distance must be the same. When you are fully prepared to count the standard,
select <Accept>.
WARNING: You must use the same geometry for counting the sample/capsule or lab
background as used for counting the thyroid and / patient background. The system
calculation assumes the same geometry when comparing counts to counts. You must also
ensure that the collimator is at a right angle to the neck phantom and the thyroid so that
it is positioned correctly for counting to retain the correct geometry. Make sure the
distance bar and positioning light are not in the counting field.
AVERTISSEMENT: Vous devez utiliser la même géométrie de comptage de
l'échantillon/capsule ou lab arrière-plan tel qu'utilisé pour le comptage de la thyroïde et /
patient arrière-plan. Le calcul de système suppose la géométrie même lorsque l'on compare
le nombre de chefs d'accusation. Vous devez également vous assurer que le collimateur est
à angle droit avec le fantôme de cou et de la thyroïde afin qu'il soit positionné correctement
pour le comptage pour conserver la géométrie correcte. Assurez-vous que la barre
d'écartement et positionnement de la lumière ne sont pas dans le champ de comptage.
10. The Counting Standard screen is now displayed. Once counting begins, ROI counts, ROI
Elapsed time and Time Remaining are indicated to the right of the counting window. When
the system finishes counting, it will stop and complete a final download of the spectrum.
The message “Counting Complete” is displayed at the bottom of the screen. Select <Next>
to return to the Thyroid Uptake screen.
NOTE: If you wish to perform a spectrum analysis, select the <Analysis> icon before
selecting <Next>.
