Question

1. if there was no image on a film that was exposed to radiation and it was processed normally, the film would appear what color?

a. white
b. blue
c. green
d. black

1. which of these imaging modalities is not digital?

a. rare earth
b. cr
c. ccr
d. dr

1. when producing digital images, how is the image seen?

a. on radiographic film
b. on a computer screen
c. on special televisions
d. on a view box

1. what is dicom used for?

a. production of radiation
b. removing scatter radiation
c. storage of digital images
d. protection from radiation exposure

Explanation:

• Question 9: In radiography, if a film is exposed to radiation but no image forms (i.e., no radiation - sensitive silver halide grains are activated), after normal processing (which removes un - exposed silver halide), the film base is black.
• Question 10: Rare - earth imaging (using rare - earth intensifying screens with film) is an analog modality. CR (Computed Radiography), CCR (which may be a less common term but is likely related to digital, similar to CR in concept), and DR (Digital Radiography) are digital.
• Question 11: Digital images are typically viewed on a computer screen. Radiographic film is for analog (non - digital) images, special televisions are not the standard for digital image viewing in this context, and view boxes are for analog film.
• Question 12: DICOM (Digital Imaging and Communications in Medicine) is a standard for the storage, communication, and retrieval of digital medical images. It is not for radiation production (a is wrong), scatter removal (b is wrong), or radiation protection (d is wrong).

Answer:

1. d. black
2. a. Rare earth
3. b. on a computer screen
4. c. storage of digital images
