Study Notes
Radiography of the Lower Limbs
- The recommended kV range for radiography of the lower limbs is not specified, but it varies depending on the anatomy being imaged.
Cassette Size for AP Foot (Dorso-Plantar Projection)
- The recommended size of the cassette for AP foot (dorso-plantar projection) during X-ray imaging is not specified, but typically ranges from 18 x 24 cm to 24 x 30 cm.
Measuring Anatomy Greater than 10 cm in Thickness
- For anatomy measuring greater than 10 cm in thickness, a high plus screen or a computed radiography (CR) system is recommended to be used during lower limb radiography.
Collimation Method
- The preferred collimation method, if the study allows it, is to use a collimator to reduce scatter radiation and improve image quality during lower limb radiography.
Grid Use in X-ray Imaging of the Foot
- A grid is not used during X-ray imaging of the foot when the part being imaged is small, such as toes, or when a non-grid technique is specified.
