AP (anteroposterior) view directs the X‑ray beam from front to back; the patient faces the X‑ray tube with their back to the detector or lies supine. It’s used when upright imaging isn’t possible but can magnify the heart and mediastinum. Lateral view is taken from the side, showing depth and anterior–posterior relationships, aiding localization of lesions, effusions, or alignment when paired with AP/PA views.

Position the patient seated at the table with the hand pronated and the palmar surface on the image receptor. Abduct the thumb away from the fingers and rest it flat so its long axis is parallel to the receptor. Center at the first MCP joint; direct the central ray perpendicular to that joint. Collimate from distal phalanx through trapezium; instruct the patient to remain still and shield as needed.

Seat the patient beside the detector. Rest the hand on the detector with the thumb abducted and placed in true lateral (medial surface against the receptor) so the thumb’s profile is perpendicular to the beam. Center the CR at the first MCP joint and collimate from distal phalanx through the base of the first metacarpal. Use appropriate exposure settings, immobilize, and apply shielding.

Yes. In the standard anatomical position (standing with palms facing forward), the thumb is lateral — located on the radial side of the hand. It lies farther from the body’s midline compared with the other fingers; the little finger is medial. Clinically, "radial" refers to the thumb-side (lateral) and "ulnar" to the little-finger side (medial), used to describe hand positions and motions.

AP and lateral are two standard radiographic views — anteroposterior (AP) and lateral — so there are two views. The AP projection passes X‑rays front‑to‑back; the lateral is perpendicular, side‑to‑side. Using both gives orthogonal perspectives to localize lesions, assess depth, and improve detection of pathology (for example in chest and extremity imaging).

In X‑ray imaging, "lateral" denotes a side-to-side view taken with the X‑ray beam passing from one side of the body to the other, producing a side profile of the anatomy. The patient’s side is placed against the detector; "left lateral" or "right lateral" names which side is nearest the film. Lateral views help localize depth, show alignment, and reveal findings hidden on front/back projections.
