Beam Quality

Question 1

What is beam “Quality”

Answer 1

Penetrating Power

Question 2

There is more penetrating power when the x-ray wavelength is ________________

Answer 2

Shorter

Question 3

X-ray power is measured in ________

Answer 3

Kilovoltage (kV)
*Peak = kVp

Question 4

Increased kVp generates new ____________
wavelengths while the other wavelengths remain.

Answer 4

Shorter

Question 5

Increased kVp generates more _______________ _________________

Answer 5

Penetrating Photons

Question 6

Increased kVP results in more __________
exposure.

Answer 6

Film

Question 7

The greater the electrical difference is between the cathode and the anode in the x-ray tube, the faster the electrons will go due to increased ______________________ .

Answer 7

Kinetic Energy
(the photons generated will have more penetrating power)

Question 8

What is Santes’ Rule?

Answer 8

The kVp needed when the film is on the table top can be calculated as follows:

[2 x patient thickness in cm] + 40 = kVp
