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
Collimator Removal/Crystal Damage The maiCAM180 is equipped with “barn door”
collimators which help limit the risk of removing collimators daily
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
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
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
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
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 (59-86F/15-30C)
Exposing the crystal to extreme temperatures can also cause irreversible damage, such as cracking
Transportation maiCAM180

Technologist safety
Transportation Basics Protecting the System from Damage
Crystal Camera
Collimator Removal/Crystal Damage The maiCAM180 has locking pins, that keep
the collimators from swinging open during transportation, and exposing the crystal
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
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
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
