The use of aluminum, gadolinium, and yttrium filters in conjunction with E-speed film was studied. The resulting radiographs were judged to be acceptable for diagnostic purposes, although clinicians showed a preference for E-speed radiographs made at reduced exposure times and for D-speed radiographs. There was no detectable difference between the radiographs produced with the various filter materials.
