Digital vs film imaging · CDA

Digital radiography reduces patient radiation dose primarily because:

  1. It uses faster exposure times
  2. It requires heavier shielding
  3. It uses high-speed film
  4. It reduces scatter radiation
Show answer and explanation

Correct answer: It uses faster exposure times

Digital systems require less exposure to produce diagnostic-quality images. This reduction in exposure time lowers patient dose.
