Where does the x-ray beam finally exit the tubehead assembly?

The last internal boundary the x-ray beam passes through as it leaves the tubehead is the aluminum filtration disks. These disks sit directly in the beam’s path inside the tubehead and remove low-energy photons, “hardening” the beam before it exits the tubehead toward the PID and patient. The unleaded window is an earlier window for the beam to escape the tube envelope, while the tubehead seal is not the beam’s exit boundary, and the PID is outside the tubehead assembly.
