  • Supine Position: Lying on the back.
  • Decubitus Position: Lying down.
  • Right Lateral Decubitus Position: Lying on the right side.
  • Median Sagittal Plane: Divides the body into equal right and left halves.
  • Erect Position: Seated or standing.
  • Posterior Aspect: Refers to the view of the patient from the back.
  • Sagittal Plane: Divides the body into right and left halves.
  • Parasagittal Plane: Divides the body into unequal right and left parts.
  • Transverse (Axial) Plane: Divides the body into superior (upper) and inferior (lower) parts.
  • Prone Position: Lying face down.
  • Flexion: Decreasing the angle of a joint.
  • Semi-recumbent Position: Posterior thorax against the cassette.
  • Abduction: Movement away from the midline of the body.

Upper Limb Radiography

  • Seated Position: Patient sits at the table for imaging; legs not under the table for upper limb imaging

Other Anatomical Terms

  • Lateral Rotation: Rotation away from the midline.
  • Pronation: Rotation of the hand to face backward.
  • Anteroposterior Projection (AP): Central ray enters the anterior aspect and exits the posterior aspect.
  • Left Lateral Projection: Central ray enters from right and exits to left sides of the body.
  • Right Lateral Projection: Central ray enters from left and exits to right sides of the body.
  • Oblique Projection: Central ray enters at an angle to the median sagittal plane.
  • Right Oblique Projection, Left Oblique Projection: The positioning described depends on the side of the body the central ray enters from.
