Radiology

2. This glass structure holds the cathode and anode. (2 words)
10. When the object of interest is raised or anatomically positioned above the image receptor
11. Another factor in patient motion, which in some cases may be useful when imaging a particular body part that is obscured by overlying anatomical structures.
12. Equipment that is used to protect someone from scatter radiation.
14. Radiation that spreads out in different directions from a radiation beam when the beam interacts with a substance, such as body tissue. (2 words)
16. A filtration to eliminate scatter radiation on the image; includes gloves, saline bags,and/or plastic bags of flour or rice.
18. This person discovered x-rays in the late 1800s.
19. This acronym is a universal rule that means to reduce the radiation to a patient as much as possible.
20. The unit used to measure the electic current that activates the x-ray tube

1. The foreshortening or elongation of a body part due to angulation of the body part, x-ray receptor, or x-ray tube.
3. This material is necessary to have in personal protective equipment in order to protect a person from radiation.
4. Radiation that is created by the photon stream outside the actual focal spot. (2 words)
5. The maximum energy in one exposure
6. The ability to differentiate fine details within the x-ray image.
7. The positive side of the x-ray tube
8. The bevel of the angled anode limits the amount of x-rays being produced beyond the edge of the anode. The intensity of the radiation is greater on the cathode side than on the anode side. This effect is called the: (3 words)
9. The portion of the x-ray image that is sharp and clearly collimated.
13. The useful beam with varying energies but enough to penetrate the patient and reach the detector (either film or detector plate)(2 words)
15. The unit found directly beneath the x-ray tube. It produces a light beam that coincides with the x-ray beam and covers the region of interest.
17. The negative side of the x-ray tube
