Evaluation of new film high-light system by comparison with conventional film.

: The 3M "High Light System" has been used in a clinical environment for one and one-half years. The inherent advantages, as well as the disadvantages, of this system are discussed. An objective comparison of the blue based HL film and the conventional Type R film was made. This comparison indicates that image quality is similar with either film and, hence, radiographs produced with either system will be of diagnostic quality.
