RAD 100 Exam 3
1. Compton scatter originates with an incident photon
interacting with the orbital of a target atom.:
electrons
2. Characteristic x-ray photons produced during the
photoelectric effect can contribute to patient
dose.: increasing
3. With Compton scattering, when the orbital electron is
dislodged, the energy of the incident photon is
and the atom is .: reduced , ionized
4. With the photoelectric effect, the incident photon is
completely by the atom when it its energy to an
inner shell electron, causing it to be ejected from the atom.:
absorbed , transfers
5. An x-rays interaction with matter correspond to the
of the pho- ton.: energy
6. Pair production occurs at energies over MeV and
photodisintegra- tion occurs at energies at or above
Mev.: 1.02 , 10
7. Low-energy x-rays tend to interact with the whole
, while pho- tons with midrange energies tent to interact with
, the orbital . High-energy photons tend to interact
with the .: atom , electrons , nucleus
8. Compton scattering reduces the energy of the x-ray and
the secondary atom.: ionizes
9. Pair production and photodisintegration do not occur in the
energy range.: diagnostic
10. Object to image receptor distance distance from the part
to the IR: Ob- ject-Image Distance (OID)
11. x-ray beam that exits the patient; made up of imaging
forming x-rays and scatter: Remnant Beam
12. negative electrode in the x-ray tube: cathode
13. digital radiographic imaging using a cassette containing
an imaging plate-
: Computed Radiography (CR)
14. solutions or gasses introduced into the body to increase
the scale of contrast: Contrast Media
15. a device that is placed between the patient and the image
receptor that absorbs scatter from the patient: Grid
16. misrepresentation of the size or shape of the object as
recorded in the radiographic image: Distortion
17. an unwanted marking on a radiographic image: artifact
