Chapter 12 Key Terms

6. A noninvasive x-ray procedure that can quantitively predict the risk of bone fracture
10. The average radiation dose to the entire active bone marrow
12. In general represents the absorbed dose to the most superficial layers of the skin
13. A partnership of medical societies whos overall common purpose is to reduce dose for pediatric patients
15. Radiation exposure received by the male and female reproductive organs

1. The practice of using fluoroscopy to determine the exact location of the central ray with respect to the patient's anatomy before taking a diagnostic exposure
2. An alternative procedure to the use of a radiographic grid for reducing scattered radiation during certain examinations
3. A personnel monitoring device that most often contains a crystalline form of lithium fluoride as its sensing material
4. An interaction that produces a satisfying result through an exchange of information
5. X-ray exposure to the skin of the patient
7. Concept used to assess the net impact of gonadal dose to an entire population due to gonadal radiation received by a segment of that population
8. The goal of this campaign is to change long-established practice by raising awareness about methods for lowering radiation dose during pediatric medical imaging examinations
9. All the deflected radiation that arises from the interaction of an x-ray beam with the atoms of a patient or any other object in the path of the beam
11. Promotes lowering the amount of radiation used in medically necessary imaging procedures and eliminating unnecessary procedures in adult medical imaging
14. An image that must be performed more than once because of human or mechanical error during the production of the initial image
