Subject field(s)
  • Tomography
DEF

A radiographic technique that selects a level in the body and blurs out structures above and below that plane, leaving a clear image of the selected anatomy.

OBS

This is accomplished by moving the x-ray tube in the opposite direction from the imaging device around a stationary fulcrum defining the plane of interest. Tube movements can be linear, curvilinear, circular, elliptical, figure eight, hypocycloidal, or trispiral.

French

Domaine(s)
  • Tomographie
DEF

Technique radiologique permettant d'obtenir l'image radiographique d'une coupe d'un organe donné.

OBS

Le principe de la tomographie consiste à déplacer en sens inverse la source de rayons X et le film selon un mouvement identique et symétrique par rapport à un plan qui constitue le plan de la coupe à étudier; seul ce dernier apparaîtra sur le cliché, les plans antérieurs ou postérieurs étant effacés. On peut, grâce à ce procédé, réaliser des séries de coupes tomographiques de profondeurs différentes, et permettant d'étudier le «volume» d'une image radiologique plane.

Spanish
