What sequential components do x-rays pass through after leaving the unleaded glass window?

Explanation:
After leaving the unleaded glass window, the x-ray beam encounters the tubehead seal first, which serves as a protective barrier inside the tubehead. Next, it passes through aluminum filtration disks to remove low-energy photons that would only add dose without improving image quality. The beam then goes through the lead collimator, which shapes and narrows the beam to the size needed for the bitewing or panoramic exposure. Finally, the beam exits through the PID, directing it toward the target area on the patient. This order—tubehead seal, aluminum filtration, lead collimator, then PID—reflects how the beam is progressively filtered and shaped before exiting the tubehead.
