Flashcards in Radiology Deck (21):
1

What is the radiology tube head often referred to as?

PID

2

What are the sizes of veterinary dental radiology film?

0, 1, 2 & 4

3

What is the film speed of veterinary dental film?

Ultra-speed film D

4

What is the rule with Dimple-dot position?

Convex side toward primary beam on coronal aspect of teeth.

5

How are veterinary dental films marked?

Small radiopague adhesive numbers are applied before exposure.

6

What would clear film represent with developing film?

Hasn't been exposed to x-ray beams; machine wasn't turned on, or burned out light

7

What would light film represent?

Underexposure; time setting too short

8

What would black film represent?

Overexposure; viewing film between develper/fixer turns film gray

9

What would a green tint represent?

Film was not properly rinsed

10

What would a brown tint represent?

Film not fixed sufficiently in the fixer.

11

Does the kVp and Ma stay the same with digital dental radiology?

Yes, you only adjust the time.

12

How many canine exposures can you get?

12

13

How many feline exposures can you get?

8

14

What are the two different patient positions for dental radiology?

Maxillary & Mandibular teeth

15

What is the parallel technique?

Mandible
Dorsal recumbency
Digital sensor is placed parallel to teeth and PID is perpendicular

16

What teeth are radiographed with a parallel technique?

Feline: 307-309 & 407-409
Canine: 307-311 & 407-411

17

What is the bisecting angle technique?

Maxillary
Ventral recumbency (head parallel to table, propped up 4-6".

18

Primary beam is at a 45-50 degree angle

True

19

The PID is held stationary, you move the patient.

False - the PID is rotated as you move around the patient.

20

What angle is the cone at for Maxillary canines?

55-60 degree. MOre horizontal angle and farther back. Separate views of each canine.

21

What angle is the cone at for mandibular canines?

70-80 degrees. Both on one exposure unless crowns are needed.
