Radiographic positioning terminology is used routinely to describe the position of the patient for taking various radiographs.
Terminology
Basic terms
- anterior
- front: front side of patient - posterior
- back: back side of patient - lateral
- as: as viewed from one side - medial
- as: as viewed towards the midline
Planes
- medial sagittal plane
- divides: divides the body into right half and left half - coronal plane
- divides: divides the body into anterior and posterior part - axial (transverse) plane
- divides: divides the body into superior and inferior part
Body positions
- erect
-: either standing or sitting - decubitus
- lying: lying down - supine
- lying: lying on back - prone
- lying: lying face-down - lateral decubitus
- lying: lying on one side- right lateral: right side touches the cassette
- left lateral: left side touches the cassette
Limb positions
- flexion
- decrease: decrease in the angle of the joint - extension
- increase: increase in the angle of the joint - abduction
- movement: movement of limb away from midline - adduction
- movement: movement of limb towards the midline - pronation
- movement: movement of hand and forearm to bring the palm facing posterior - supination
- movement: movement of hand and forearm to bring the palm facing anterior
Projections
- antero-posterior
- central: central ray passes from anterior to posterior - postero-anterior
- central: central ray passes from posterior to anterior - lateral
- central: central ray passes from one side of body to the other through the axial plane - oblique
- central: central ray passes through the body/body part through a plane which is at an angle to the transverse plane/coronal plane
