The ottonello method is used to see a front view image of cervical 1-7 number. The study found a systematic examination method to find a better image through an experiment using metronome. The results are as follows: In an evaluation of MTF, when used 0.5 standard of MTF, oral explanation resulted 1.2 LP/mm, Moderato-100 1.4 LP/mm, Allegro-138 1.6 LP/mm, Presto-184 2.4 LP/mm. Among them presto-184 showed the highest sharpness with 2.4 LP/mm. In an image reading by a medicine doctor of radiology, when oral explanation was 17%, Moderato-100 15%, Allegro-138 18%, Presto-184 50%. Among themprest-184 was evaluated as the best image. The result of was a method to reduce an image repeat, patients radiation exposure, patients waiting time for examination, material and so on.
