Study Notes

Heel Effect in X-Ray Imaging

The heel effect is crucial for imaging structures with varying thickness or density.
Placing the X-ray tube's cathode side over the thicker anatomical region ensures more even radiation exposure on the image receptor.
Cathode and anode directions are often marked on the X-ray tube housing, sometimes near the connecting cables.
