SAFETY PROTOCOLS FOR CBCT SCAN
There are certain protocol to be followed before you enter CBCT scan room.
All have to follow ALARA principle.Means As Low As Reasonably Achievable.Below we have explained clearly,how we follow ALARA principle.
We ask the patient to remove their ear rings,nose piercings,clips on their hair.And have to put the chains back.These protocols are asked to follow ,because these items may interrupt the scan.Items will be given to respective person once scan is completed.
