"blank" is the process of informing the patient about dental imaging procedures.
"blank" is permission granted by a patient after he or she has been informed about the particulars of the procedure.
"blank" means that a person is accountable, or legally responsible.
"blank" ensures that high-quality diagnostics radiographs are produced.
Specific tests that are used to ensure quality in dental x-ray equipment, supplies, and fil processing are
quality control test
A "Blank" is used to demonstrate film densities and contrast.

Positioning device or film-holder
An illuminated boxlike device used to view radiographs.
What are the three major categories of legal considerations regarding the use of images in dentistry?
- 1. federal and state regulations regarding x-ray equipment and its use
- 2. licensure for individuals who expose dental images
- 3. risk management for avoiding potential lawsuits
