17. Tell the patient to return at a specific time.
18. Select <Back> to return to the Study Selection screen.
19. Select <Back> to return to the Select or Add a Patient screen if you wish to add another
patient or are counting the thyroid of a returning patient.
NOTE: You can now use the system for other functions by returning to the Home screen
and making the appropriate selection.
20. When the patient returns at the specified time, select <Testing> and then <Thyroid
Uptake>.
21. Highlight the patient on the Select or Add a Patient screen and select <Next>.
NOTE: You can use the search options at the top of the screen to find the desired patient
by entering the last name and/or ID number and selecting <Search> (magnifying glass).
22. Confirm the patient’s name, ID and study on the Study Selection screen. Select <Next> to
advance to the Thyroid Uptake screen.
23. Select <Count Thyroid> and then position the patient’s thyroid with the same geometry as
used for counting the dose. The distance bar and 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. Select <Accept> to begin counting the
patient thyroid.
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 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 par rapport à la thyroïde alors qu'il
est 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.
24. When the counting is complete, 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>.
