DEHY 123 - Radiology

3 CR
This course includes the study of radiography theory and the techniques of exposing, processing, and mounting radiographs. Students also acquire the interpretation skills needed to utilize radiographs successfully during patient care. Emphasis is placed on legal, ethical and safety practices using the ALARA principle. In the lab portion, students learn safety, waste management and quality assurance techniques, as well as intraoral and extraoral imaging techniques with multiple film holding devices. Students complete several practice image series on DXTTR mannequins, including the full mouth, vertical bitewing, and special patient techniques. Successful completion of this course is mandatory for continuing in the program. Lab Fee
