1. Safety and Precautions
Operation and Transportation maiCAM180

2. Operation maiCAM180
Collimators
Crystals
Operating Temperatures
Gantry Motions
Patient Safety
Technologist Safety

3. Collimator Removal/Crystal Damage
 If performing intrinsic floods daily collimators must be
removed everyday
 Caution must be used every time the collimator is
removed and the crystal is left unprotected
 NaI Crystal
 Solid-state
 Hygroscopic
 Hermetically sealed
 Single most expensive component of gamma camera

4. Collimator Removal/Crystal Damage
 The maiCAM180 is equipped with “barn door”
collimators which help limit the risk of removing
collimators daily

5. Patient Safety/Gantry Motions
 The maiCAM180 gantry will perform automatic
motions during setup, acquisition, and completion of
SPECT studies
 A patient belt will help keep the patient’s body from
being struck by the detectors when in automatic
motion

6. Patient Safety/Gantry Motions
 Contact pads on both detector heads will suspend
motion if the detector hits the patient
 There are no contact pads on the bottom of the
detectors, so be sure to pay close attention to the
location of the patient’s legs when positioning patient
along vertical axis

7. Patient Safety/Gantry Motions
 There are 3 Emergency Stops (E-Stops) on the
maiCAM180 which disable motion if the automatic
gantry motion is endangering the patient due to
positioning
 Once imaging has begun, the patient should be
observed closely to be sure that the patient does not
move into the gantry orbit

8. Technologist Safety/Gantry Motions
 The technologist should stay clear of the gantry
during all gantry movements
 The technologist should use caution around the
“bear-claw” located behind the detectors of the
maiCAM180 (pictured below), which is a possible
pinch point during gantry motion of all kind

9. Temperature Fluctuation
 Fluctuations in room temperature will affect image
quality due to varying temperatures of the crystal
 When the crystal temperature fluctuates outside of
recommended operating temperature, proper
scintillation is inhibited and image quality is poor
 Whether a crystal has been effected by temperature
changes can usually be seen on a uniformity flood
 Operating Ambient Temperature (59-86 F/15-30 C)
 Exposing the crystal to extreme temperatures can
also cause irreversible damage, such as cracking

10. Transportation maiCAM180
Crystal damage
Camera damage
Weather precautions
Technologist safety

11. Transportation Basics
 Protecting the System from Damage
 Crystal
 Camera

12. Collimator Removal/Crystal Damage
 The maiCAM180 has locking pins, that keep the
collimators from swinging open during
transportation, and exposing the crystal

13. Gantry Motions/Camera Safety
 There is a locking pin on the gantry “bear-claw” to
prevent the gantry from swinging side to side when
camera is in transport and has lost power supply
 Be sure the locking pin is in place whenever camera
is being transported so that gantry is not damaged

14. Transportation Basics
 When transporting the maiCAM180, it is important to
protect the system from outdoor elements
 A waterproof rain cover should be used on the
system when transporting in rainy conditions
 A thermal cover should be used to protect the
system from extreme cold conditions

15. Transportation Basics
 Be sure transportation directions are followed to
keep yourself and the camera safe at all times
 When camera is being moved, front wheels should
be set to roll and back wheels to swivel
 Be sure when going down inclines, no wheels are
set to swivel
 Never “jump” a curb with the maiCAM180 – this can
cause severe damage to the system
 Whenever traveling along uneven ground/curbs, use a
metal plate to create a level ground for the camera to
move on
