TABLE 2.

Example from Profile of Mitigating Steps

Parameter	Entity/actor	Specification
PET scanner calibration	Technologist	Must perform daily/weekly/monthly scanner quality assurance and vendor-recommended maintenance procedures (e.g., replace weak transmission sources for dedicated PET scanner); must ensure that output values are acceptable and manually entered on form/electronic database
PET scanner calibration constancy check	Technologist	Must perform constancy phantom (e.g., 68Ge cylinder) scan (preferably NIST-traceable or equivalent to gather information on uniformity as well) at least weekly and after each calibration
Radionuclide calibrator	Physicist	Must be calibrated to 18F using NIST-traceable source or equivalent either by site or by calibrator manufacturer

NIST = National Institute of Standards and Technology.
