Check the length of all patient health lines (IV tubing, oxygen line, etc.) and make sure they
accommodate cradle travel. Position these lines so they cannot catch on anything within the
patient vicinity or between the table and gantry during cradle travel.
Chapter 3 Safety
CAUTION
When using the external laser alignment light for patient positioning purposes, be
aware that the patient's elevation may be slightly lower with the cradle extended
than with the cradle fully retracted. This is because the cradle may bend slightly
under a patient's weight. This difference should be taken into consideration for
applications where patient position information is critical, such as Treatment
Planning. To minimize these effects, after using the external laser alignment
system to position the patient, advance the patient to the CT scan plane. Turn on
the CT alignment lights to determine if they line up with the markers on the
patient. If necessary, compensate for the bend in the cradle by elevating the
table. When the CT alignment lights line up with the markers, set the landmark
for the scan using the Internal laser alignment light.
WARNING
WHEN USING PATIENT POSITIONING ACCESSORIES AND STRAPS, MAKE
SURE THERE ARE NO AREAS WHICH MIGHT CAUSE A PINCH POINT OR
INTERFERE WITH PATIENT TUBING OR IV.
WARNING
CHECK TO MAKE SURE THE POWER INJECTOR HAS ENOUGH IV TUBING
TO ALLOW FREE MOVEMENT OF THE CRADLE. MAKE SURE THE UNIT
ITSELF DOES NOT INTERFERE WITH TABLE TRAVEL. ENSURE EXCESS
TUBING LENGTH IS SECURED TO THE TABLE TOP. DO NOT LOOP
ADDITIONAL IV TUBING IN THE PATIENT'S FINGERS.
WARNING
THE PATIENT POSITIONING STRAPS PROVIDED WITH THE SYSTEM DO
NOT SUPPORT THE FULL WEIGHT OF THE PATIENT. PATIENT
POSITIONING STRAPS SHOULD BE USED TO AID IN PATIENT
POSITIONING AND ARE NOT MEANT TO FULLY RESTRAIN THE PATIENT.
CAUTION
Gantry straps are designed to hold accessory cables that connect to the gantry
rear panel. Do not use for lifting or support.
CAUTION
Gantry straps should only be used for holding accessory cables that connect to
the gantry rear panel. Placing injector lines through the gantry straps could cause
interference issues and patient harm.
