Photoelectric Absorption Flashcards
Photoelectric absorption is likely to occur when an X-Ray photon interacts with a:
Inner Shell Electron
What are the primary by products of a photoelectric absorption interaction:
Free Electron
Characteristic photon
The photoelectric effect adds to patient dose through an event called:
Ionization
Photoelectric interactions occuring during a radiographic procedure
Image Quality
Patient dose
Photoelectric absorption influences radiographic image quality and results in increased:
Image Contrast
How does increasing kilovoltage peak (kvp)affect the proportion of photoelectric absorption events that occur in a patient’s tissues:
increasing kvp decreases the proportion of photoelectric absorption
Which of the following X-ray interactions creates a free electron called a “Photoelectron”:
Photoelectric Effect
Which of the following human tissues experience the most of photoelectric absorption events during a radiographic procedure:
Bone TIssue
What characteristics of iodine and barium contrast agents is responsible for increasing the rate of radiation absorption compared to human tissues:
High atomic number
Photoelectric absorption included which of the following effect
Increased patient dose and increased image quality
