Quality Control

Well-counter calibration data of a positron emission tomography (PET) scanner are applied for:

The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the:

Spatial resolution and spatial linearity of a gamma-camera is assessed with a 4-quadrant bar phantom which consists of four sectors of lead bars and intervening plastic strips:

The quality control procedure known as survey meter calibration is usually performed by:

Increasing the thickness of the scintillation detector will result in the detector:

If generator elute contains 635 mCi of Tc-99m, what is the maximum amount of Mo-99 allowed? (0.15 uCi Mo-99 per mCi Tc-99m)

The extrinsic flood image evaluates the uniformity of:

When performing daily intrinsic floods, a point source of Tc-99m is placed five crystal dimensions away and centered over the detector. A point source should produce a measured counting rate not greater than:

The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called:

Calibration, sensitivity/constancy, efficiency, chi-square, and energy resolution are quality control procedures performed to ensure proper operation of the:
