Digital radiography

Question 1

what are the 2 types of digital radiography?

Answer 1

Indirect (iDR)
Direct (dDR)

Question 2

briefly describe CR?

Answer 2

• X-rays interact on the phosphor plate and cause excitation of the electrons within the phosphor layer

-Electrons get “trapped” in the phosphor crytals ie stay in an excited state

• A laser is used to stimulate the trapped electrons, enabling them to release the trapped energy as blue light photons

-Emitted photons and location are recorded and converted into an image

Question 3

briefly describe direct radiography

Answer 3

-uses x-ray–sensitive plates that directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate
