A system and method for creating a three dimensional cross sectional image of an object by the reconstruction of its projections that have been iteratively refined through mathematical transformations and modifications in object space and Fourier space is disclosed. A primary benefit of the method is radiation dose reduction since the invention can produce an image of a desired quality with a fewer number projections than seen with conventional methods.
Linvention concerne un système et un procédé de création dune image de section tridimensionnelle d'un objet par la reconstruction de ses projections qui ont été affinées de manière itérative par des transformations mathématiques et des modifications dans l'espace d'objet et l'espace de Fourier. Un avantage principal du procédé est la réduction de la dose de rayonnement étant donné que l'invention peut produire une image d'une qualité souhaitée avec un plus petit nombre de projections qu'avec les procédés classiques.
