When performing a physics survey or equipment evaluation on a unit with multiple target/filter combinations, what tests or measurements must be performed for each combination?

For a unit with multiple target/filter combinations, the following tests must be performed for each clinically used target/filter combination:

• Focal spot condition (for different target materials [tracks] only)

• X-ray field/light field/image receptor/compression paddle alignment (for different target materials [tracks] only)

• Beam quality and half-value layer

• System artifacts
