4) Positioning
5) Geometric distortion
6) Centering
7) Collimation
8) Radiographic density

Question 2

1) Patient preparation:

Answer 2

Ren pels, tør. Fastet (tom GI). Halsbånd væk, godt nok sederet.

Question 3

2) Object presentation

Answer 3

Centér på det du vil se på, få alt interessant med på billede, tag ikke for meget med.

Question 4

3) Postioning

Answer 4

Den skal ligge lige!

Question 5

4) Respiratory phase

Answer 5

Thorax billede: Max inspiration (diaphragma ved T12).

Abdomen: Max ekspiration.

Question 6

5) Distortion

Answer 6

Change of an object’s true size and shape
due to it’s location in relation to the X-ray
beam and the image receptor/film

Fx ben i luften vil se fucked ud.

Question 7

6) Centering

Answer 7

Gir sig selv tumbe

Question 8

7) Collimation

Answer 8

Gør det !! og gør det godt.

Question 9

8) Radiographic density

Answer 9

Nok røntgenstråler…

Question 10

9) Contrast (kV)

Answer 10

Lav kV: knogler (få grå nuancer, sort, grå, hvid)

Høj kV: bløddele (vi vil have mange grå nuancer)

Question 11

10) Detailing (kV)

Answer 11

The contour of an

anatomic structure is definable

Question 12

11) Image processing

Answer 12

Hvordan det fremstilles… manuel, maskine, digital

Question 13

12) Radiation safety

Answer 13

• Indikation
• Beskyttelese og afstand
• Optimal teknik
• Evaluering og korrigering af suboptimale billeder
