Study Notes

Radiography Techniques for Upper Limb Procedures

Recommended focus to film distance (FFD) for upper limb procedures is 100 cm.

Positioning for Hand X-ray

For PA (Posteroanterior) fingers X-ray, the patient should be seated comfortably with the palm facing down on the imaging plate.

Positioning for Oblique Finger X-ray

PA oblique fingers X-ray requires the fingers to be rotated 45 degrees laterally, with the hand in contact with the imaging receptor.

Radiation Safety Practices

The most effective practice for reducing unnecessary radiation exposure is utilizing shielding devices, such as lead aprons, whenever possible.

Shielding for Recumbent Patients

Shielding should be applied to recumbent patients during upper limb examinations to protect gonadal regions and reduce radiation exposure, especially when the beam is directed near these areas.
