Cet outil d'analyse harmonique découle directement des travaux de Joseph Fourier (1768-1830), fameux mathématicien et physicien originaire d'Auxerre. Grâce au calcul de la transformée de Fourier inverse, il est alors possible de visualiser le domaine spatial associé à ce domaine de Fourier, bref de reconstruire l'image de l'intérieur du corps selon le plan de coupe choisi Au sein de cette image ,
