x-ray

Question 1

energy in an x-ray

Answer 1

electromagnetic

Question 2

what type of image is an x-ray

Answer 2

2D projection image

Question 3

3 parts in forming an x-ray

Answer 3

filament, cathode, anode

Question 4

filiment

Answer 4

has a current pass through it heated to 2000 degree c

Question 5

cathode

Answer 5

when heated the electron leaves the cathode

Question 6

anode

Answer 6

electron cloud hits the anode losing energy and creating the image

Question 7

small focal spot

Answer 7

small fov
better spacial resolution

Question 8

3 factors modified at the control panel

Answer 8

accelerating voltage
tube current
duration of exposure

Question 9

3 ways in which photons interact with tissue

Answer 9

penetrate and pass-through
interact and be absorbed
interact and scatter

Question 10

photoelectric effect

Answer 10

energy from x-ray photon is absorbed by the body

Question 11

what attenuates signal the most muscle fat or bone

Answer 11

bone muscule fat
low attenuation is darker

Question 12

increase SNR

Answer 12

adjust tube current and exposure time

Question 13

increase spatial resolution

Answer 13

smaller focal spot
move patient closer to the detector
