Question

10. Fill in the blank: Computed radiography cassettes can sit for _____ between exposures.
    1. A few hours
    2. A few days
    3. Up to one year
    4. An unlimited time

11. Backscatter radiation artifacts can occur more readily in digital imaging because of the:
    1. Large data file sizes
    2. Techniques used
    3. Highly sensitive receptors
    4. Partitioning errors

Answer 1

Ans) option b is correct.

Computer radiography cassette is digital radiography based on cassette, which will make use of luminescence screens which is photo stimulated in order to capture X-ray images. Also,only for few days computed radiography cassette can sit after exposure.

Ans) option C is correct.

Backscatter radiation is scattered by the object which is present on specimen film side. And due to presence of high sensitive Receptor in blackscatter radiation they are readily used in digital imaging.
