Study Notes
Radiography of the Lower Limbs
- Recommended kV range for lower limb radiography is typically between 60-80 kV.
- Preferred collimation is rectangular collimation when allowed by the study, to limit radiation exposure and improve image quality.
- Grids should be used for lower limb radiography when the body part exceeds 10 cm in thickness, as they help reduce scatter radiation.
- Multiple exposures can be placed on the same Imaging Plate (IP), allowing efficient use of the imaging equipment.
- The recommended cassette size for an AP foot (dorso-plantar projection) is 24 cm x 30 cm.
- For lower limb radiography, the recommended focal spot size is small (0.3 mm) to enhance image resolution and detail.
- Grids should be utilized for lower limb radiography when the body part exceeds 10 cm in thickness, mitigating scatter radiation effects.
- The ideal cassette size for an AP foot (dorso-plantar projection) is 24 cm x 30 cm, providing optimal imaging dimensions.
