What is the primary function of the grid in grid radiography?
What is the primary function of the grid in grid radiography?
- To absorb primary radiation
- To reduce the transmission of scattered x-rays (correct)
- To scatter x-ray photons in all directions
- To amplify the intensity of x-ray photons
Why do obliquely angled photons have a higher probability of striking the grid septa?
Why do obliquely angled photons have a higher probability of striking the grid septa?
- Because they have a higher energy than primary radiation
- Because they have a shorter path length through the patient
- Because they are scattered in multiple directions (correct)
- Because they have a lower intensity than primary radiation
What is the result of reducing the transmission of scattered x-rays in grid radiography?
What is the result of reducing the transmission of scattered x-rays in grid radiography?
- Increased radiation dose penalty
- Improved image contrast (correct)
- Increased primary transmission
- Reduced x-ray intensity at the detector
