| Question | Answer |
|---|---|
| Any filtration that occurs outside the tube and housing before the image receptor | added filtration |
| Used to even out unequal densities | compensating filter |
| The use of two or more materials to complement one another in their absorbing abilities; also known as K-edge filters. | compound filter |
| Any material designed to effectively absorb photons from the x-ray beam | filter |
| The amount of absorbing material that will reduce the intensity of the primary beam to one-half its original value. | half-value layer (HVL) |
| Results from the composition of the tube and housing | inherent filtration |
| The use of two or more materials to complement one another in their absorbing abilities; also known as compound filters. | K-edge filter |
| A type of compound filter consisting of tin, copper, and aluminum, in that order, typically used in radiation therapy. | thoraeus filter |
| The sum of inherent and added filtration | total filtration |
| A type of compensating filter used to even out densities such as the mediastinum | trough filter |
| A type of compensating filter used to even out densities such as in the foot or lower extremities | wedge filter |
