X-ray Production Ch 8

Question 1

The energy of motion

Answer 1

Kinetic Energy

Question 2

KE Formula

Answer 2

KE = ½mv2

Question 3

Electrons travelling from cathode to anode

Answer 3

Projectile Electron

Question 4

Three Effects if Projectile Electron

Answer 4

• The production of heat
• The formation of characteristics xrays
• The formation of bremsstrahlung xrays

Question 5

constant excitation & return of

outer-shell electrons

Answer 5

Anode Heat

Question 6

Efficiency of X-ray Production

Answer 6

• It is independent of the tube current

- It increases with increasing kVp

Question 7

It is emitted when an outer-shell electron

fills an inner-shell void

Answer 7

Characteristic Radiation

Question 8

What x-rays of tungsten are useful for imaging

Answer 8

K- Characteristics

Question 9

X-rays resulting from electron transition to

the K shell

Answer 9

K X-rays

Question 10

X-rays resulting from electron transition to

the L shell

Answer 10

L X-rays

Question 11

It is produced when a projectile electron is
slowed by the electric field of a target atom
nucleus, “Slow down radiation”

Answer 11

Bremsstrahlung Radiation

Question 12

It results when the projectile electrons loses
all its KE & simply drifts away from the
nucleus

Answer 12

High-Energy Bremsstrahlung X-ray

Question 13

It results when the projectile electrons are

barely influenced by the nucleus

Answer 13

Low-Energy Bremsstrahlung X-ray

Question 18

It can be graphed as the number of x-rays

for each increment of energy in keV

Answer 18

X-ray Emission Spectrum

Question 19

A plot of the frequency with which 
characteristic x-rays are emitted as a 
function of energy

Answer 19
