16
Q

For the systems of the cassetteless serial film changers, both systems used what kind of intensifying screens?

A

Stationary intensifying screens

17
Q

This type of cassetteless film changer operates on the same principle as a photographic camera.

A

Roll film changers

18
Q

Roll-films are usually supplied in ______ lengths

A

50 ft

19
Q

For the roll film changers, what area do they usually expose?

A

14” x 14” area allowing approximately 43
exposures per roll

20
Q

In this changer, Film is threaded through the machine past the exposure area to another spool, which stores the exposed film

A

Roll-film changer

21
Q

This type of changer uses single or cut sheets
of x-ray film for each exposure

A

Cut-film changers

22
Q

What are the 2 types of supply magazines in a cut-film changer?

A

Interweaving and S-stack loading magazine

23
Q

What is the difference between the interweaving and s-stack loading magazine

A

I - each film must be positioned
between 2 metals or plastic dividers

S - has no dividers

24
Q

What are the 2 types of stand?

26
Q

What is the c-arm mount?

A

Allows a variety of positions in which the changer may be placed

27
Q

What are the 2 types of plane imaging?

A

Single plain and Biplane

28
Q

Difference between single plane and biplane imaging

A

S - employs one film changer and one radiographic tube

B - uses two x-ray tubes in conjunction with two film changers

29
Q

Advantage of using single-plane filming

A

Has an excellent film quality over the biplane film changer

30
Q

In the ___________ plane filming, the X-ray tube and the film changer need to be repositioned for the second view, and two injections are required in AP and Lat projections.

A

Single-Plane Filming

31
Q

Advantages of Dryview Laser Printer

A
  1. Outstanding diagnostic image quality
  2. Minimize noise and improved density uniformity in the emulsion.
  3. Easy film loading and handling
  4. No wet film processor is required
  5. Films can be loaded in full room light
  6. Film recognition technology, recognize film type, size, and lot as well as the number of sheets remaining.
