anode heel effect

Question 1

• radiographic phenomenon that affects the intensity of the x-ray beam
  • refers to the lower field intensity towards the anode in comparison to the cathode due to lower x-ray emissions from the target material at angles perpendicular to the electron beam.

Answer 1

anode heel effect

Question 2

• Increases the surface area
  of the focal spot, which increases ability of anode to absorb heat
• Decreases the effective
  focal spot size, which increases spatial resolution

Answer 2

anode angle
