I am a general dentist I am using digital x-ray x-ray is the same but the file is digital phosphate plate you can use cmos digital sensor plate only difference is you need to put phosphate plate into scanner to scan which takes 1 to 2 minutes the cmos digital plate only takes seconds to get on the screen I don't think more people still use traditional developing films which involing a lot of chemical solution and waste It's one of my best investments for dental office
