The three standard ankle X‑ray views are anteroposterior (AP) — showing the distal tibia, fibula and joint space; lateral — profiling the talus, calcaneus and posterior tibia; and mortise (an AP with 15–20° internal rotation) — which opens the ankle mortise to better show the tibiofibular relationship and detect subtle fractures, syndesmotic injury or joint-space abnormalities.

Ankle X‑rays are usually taken in three standard positions: AP (anteroposterior) with the leg extended and the foot dorsiflexed so the ankle is at 90° to the tibia; lateral with the limb turned so the medial and lateral malleoli are superimposed; and mortise view with the foot internally rotated about 15–20° to open the joint space. Weight‑bearing views may be added.

The three common X‑ray views are anteroposterior (AP), posteroanterior (PA), and lateral. AP projects X‑rays front-to-back, used when patients can’t stand. PA projects back-to-front, standard for chest films with less heart magnification. Lateral captures side-to-side anatomy, helping localize lesions and assess depth. Together they provide complementary frontal and profile information for diagnosis.

The three standard foot X‑ray views are anteroposterior (AP or dorsoplantar) — for metatarsal and tarsal alignment; lateral — showing the calcaneus, talus, and sagittal profile; and oblique (typically 30–45°) — ideal for visualizing metatarsal fractures and joint spaces. Weight‑bearing versions of these views may be used to assess alignment and deformities under load.

A 3‑view radiograph is a set of three X‑ray images of the same body part taken from different directions—commonly AP/PA, lateral, and an oblique or specialized view. Using three planes improves visualization of bones, joints and soft tissues, increasing detection of fractures, dislocations or alignment issues and reducing the chance of missed injuries, aiding clinical decision‑making.

Common types of X‑rays include: - Chest X‑ray: quick study that evaluates lungs, heart size, airspace disease, fractures, or fluid. - Dental X‑ray: intraoral or panoramic images to detect cavities, impacted teeth, bone loss, and root issues. - Mammography: low‑dose specialized breast X‑rays for routine screening and diagnostic views of lumps. Each uses different techniques and radiation doses.
