摘錄自《Oral Radiology Principles and Interpretation》Ch4 Digital Imaging p41:Digital systems also have many disadvantages compared with film. The initial expense of setting up a digital imaging system is relatively high. Certain components, such as the electronic x-ray receptor used in some intraoral systems, are susceptible to rough handling and are costly to replace. Because digital systems use evolving technologies, there is a risk—perhaps even a likelihood—of systems becoming obsolete or manufacturers going out of business. The excellent image quality and comparatively low cost of a properly exposed and processed film keeps film-based radiography competitive with digital alternatives.
