Record 2 1998-05-29

English

Subject field(s)
  • Medical Instruments and Devices
  • Tomography
CONT

The problems with projection imaging can be overcome by acquiring tomographic data with a rotating gamma camera and then correcting for attenuation in a tomographic reconstruction. This method is called single-photon emission computed tomography(SPECT).

French

Domaine(s)
  • Instruments et appareillages médicaux
  • Tomographie
CONT

L'utilisation d'une gamma-caméra tournante pour l'acquisition des projections nécessaires à une reconstruction tomographique ultérieure demande des précautions particulières et un contrôle de qualité strict, faute de quoi des artefacts sont à craindre, qui risquent d'enlever à l'examen toute signification.

Key term(s)
