Anode Heal Effect

These flashcards cover key terminology related to the Anode Heal Effect in radiography, explaining various phenomena, relationships, and conditions affecting x-ray beam intensity.

Anode Heal Effect

A radiographic phenomenon that affects the intensity of the x-ray beam across the x-ray field.

Anode Angle

The angle of the anode in general radiography, usually between six and twenty degrees, that impacts beam intensity.

Focal Spot

The area on the anode surface from which the x-ray beam is produced; a larger focal spot increases heat absorption.

X-ray Beam Intensity

The number of x-ray photons present in the beam; higher on the cathode side and lower on the anode side due to the anode heel effect.

Cathode Side

The side of the x-ray beam that has higher intensity; it produces more x-ray photons than the anode side.

Anode Side

The side of the x-ray beam that has lower intensity; it experiences a decrease in the number of x-ray photons due to the anode heel effect.

Spatial Resolution

The ability to distinguish small details in a radiograph, which improves with a decreased effective focal spot size.

Inverse Relationship

A relationship where one variable increases as the other decreases; such as between anode angle and anode heel effect.

Standard SID

Source to Image Distance; changes in SID can affect the extent of the anode heel effect.

Field Size

The dimensions of the area being radiographed; increasing the field size increases the anode heel effect.
