Question

If you are going to put more than one image on a CR cassette, which of the following is true?

1. The unexposed areas must be covered with lead
2. Four collimated borders must be around each image
3. The same exposure must be used for each image

A. 1 & 2 only
B. 1 & 3 only
C. 2 & 3 only
D. 1, 2 & 3

Answer 1

When placing multiple images on a CR cassette, it is correct to cover unexposed areas with lead and ensure each image has four collimated borders. It is not necessary to use the same exposure for each image.

Step-by-step explanation:

When you are going to put more than one image on a CR (Computed Radiography) cassette, the following statements hold true:

• The unexposed areas must be covered with lead to prevent scatter radiation from fogging the parts of the imaging plate not being used for the current image.
• Each image should have four collimated borders; this aids in reducing the patient's exposure to radiation and improves image quality.
• The same exposure for each image is not a requirement; exposure settings can be adjusted according to the specifics of each image needed, such as the body part being imaged and the size of the patient.

Thus, the correct answers are the statements 1 and 2. Therefore, option A (1 & 2 only) is the right answer.
