Added filtration in the x-ray tubehead protects the?

Added filtration in the x-ray tubehead is primarily designed to protect the patient from unnecessary radiation exposure. The process involves using materials, typically aluminum, to absorb low-energy photons that do not contribute to the quality of the x-ray image but do increase the radiation dose the patient receives. By filtering out these low-energy photons, only higher-energy, more penetrating x-rays pass through, which are necessary for producing clearer and more diagnostic images while minimizing the amount of radiation exposure to the patient’s tissues.

This practice aligns with the principle of ALARA (As Low As Reasonably Achievable), which is fundamental in radiation safety, as it emphasizes reducing radiation doses to protect individuals receiving x-rays. Therefore, while added filtration serves multiple roles, its primary protective function is safeguarding the patient from excessive and potentially harmful radiation.
