TID 10047 Attenuators

This template describes the attenuators present during an exam. The attenuators are different from the filters in that filters are intended to modify the radiation (e.g., bowtie filters, spectral filters, etc.) while attenuators may modify the radiation, but this is not the intended function (e.g., patient support, table pad, etc.).

Attenuators do not move with the associated X-Ray source (within an X-Ray tube). Attenuating material that moves with an X-Ray source is referred to as a Filter and is described in TID 10046.
