Digital radiology may represent the greatest technological advance in medical imaging over the last decade. The use of photographic films for x- ray imaging will be obsolete in a few years. An appropriate analogy that is easy to understand is the replacement of typical film cameras with digital cameras. Images can be taken, immediately examined, deleted, corrected, and subsequently sent to a network of computers.
The benefits from digital radiology are enormous. It will make the facility filmless. The referring dentist can view the requested image on a desktop personal computer, often with the report, just minutes after the examination was performed. The images are no longer held in a single location; they can be seen simultaneously by dentists and specialists in different locations. In addition, the patient can have all his or her xrays on a compact disk to take to another dentist or specialist.
Another benefit to this form of x-ray is that the radiation that is emitted is very low. If you watch television daily, you are exposed to more radiation! The new X-rays, used by an estimated 5 percent of dentists, are safer than the old method because they emit up to 90 percent less radiation. Six images of teeth can be taken for the same amount of radiation exposure it takes to process one piece of conventional film. |
