  • Marker should never obscure anatomy
  • Marker should be placed in the exposure field on the edge of the collimation border
  • Marker should be placed outside of any lead shielding
25
What is a radiograph?
The image recorded by exposing any of the image receptors to x-rays
26
What are the primary factors considered to establish correct foundation technique?
* Milliampere-seconds (mAs) * Kilovolt peak (kVp) * Source-to-image receptor distance (SID) * Relative patient or part thickness

Source-to-Image Receptor Distance
28
What is the recommended minimum Source-to-Skin Distance (SSD)?
12 inches (<30 cm)
29
What is the purpose of gonadal shielding?
To reduce radiation exposure to the patient's reproductive organs

38
What BMI range is classified as obese?
30 to 39.9 ## Footnote A BMI of 40+ is classified as morbidly obese.
