[2025-10-01T17:12:45.796334] [PI reasoning] **Answering dental radiology question**

I need to address a dental radiology question regarding filtration in radiography. The purpose of adding aluminum filters is to remove low-energy (long wavelength) photons, which can increase skin dose and degrade image quality. So, option B, which suggests removing long wavelength photons, is correct. Low energy relates to long wavelengths, while high energy corresponds to short wavelengths. Now, I should look for reliable sources to support this with citations.
