How do you get a foot oblique view?

Patient position

  1. the patient may be supine or upright depending on comfort.
  2. the affected leg must be flexed enough that the plantar aspect of the foot is resting on the image receptor.
  3. the foot is medially rotated until the plantar surface sits at a 45° angle to the image receptor.

What does the AP oblique of the foot show?

Foot AP Oblique (Medial Rotation) Purpose and Structures Shown To show interspaces between the following: cuboid and calcaneus; cuboid and fourth and fifth metatarsals; cuboid and lateral cuneiform; and talus and navicular bone. A greater rotation can be helpful in demonstrating joint spaces of the foot.

Why do we use oblique view in X rays?

The oblique hand view is requested for diagnosing a variety of clinical indications such as rheumatoid arthritis, osteoarthritis, suspected fracture or dislocation and localizing foreign bodies.

What oblique view is most commonly used for the foot?

The anterior-posterior medial oblique view requires the foot to be obliquely positioned 30 to 40 degrees. Lateral radiograph requires the patient to be recumbent on the affected side with the knee flexed. The plantar surface of the foot is perpendicular to the image receptor, thereby acquiring a true lateral image.

What is the meaning of oblique projection?

An oblique projection is a parallel projection in which the lines of sight are not perpendicular to the projection plane. Commonly used oblique projections orient the projection plane to be perpendicular to a coordinate axis, while moving the lines of sight to intersect two additional sides of the object.

What is a 3 view xray?

Three-view thoracic radiography is often used to evaluate patients for pulmonary metastatic disease.

What are the problems with oblique projection?

Cons: objects can look distorted if careful choice not made about position of projection plane (e.g., circles become ellipses) lack of foreshortening (not realistic looking)

What are the types of oblique projection?

Main Types of Oblique Projections

  • Cavalier: Angle between projectors and projection plane is 45o. Perpendicular faces are projected at full scale.
  • Cabinet: Angle between projectors and projection plane is arctan(2) = 63.4o. Perpendicular faces are projected at 50% scale.
