Radiography

The actual picture taken of bones is a/an:

• x-ray.

• radiograph.

• electrocardiograph

• gamma ray.

Radiopaque may indicate the presence of hard tissue by appearing:

• black to dark grey in colour.

• white to light grey in colour.

• red to orange in colour.

• green to blue in colour.

Number of x-ray beams passed in a time is:

• mA

• kV

• LAT

• AP

If the mA is 180 and the time (s) is 1.5 the mAs is –

• 181.5

• 90

• 200

• 270

If the screen has not got good, even contact with the film the resulting image will be:

• Unaffected

• Black

• Blurred

• Pale

What type of film needs to be loaded into a cassette?

• Screen film

• Non-screen film

X-ray film has an expiry date?

• True

• False

Which of the statements about the primary beam are accurate?

• High energy, invisible, travels in straight lines

• ALow energy, invisible, travels in straight lines

• High energy, visible, can travel round corners

• Low energy, visible, travels in straight lines

The Film Focal Distance (FFD) should…

• Be altered depending on the size of the patient

• Stay consistent

• Be altered depending on the mA and kV selected
