L'imagerie médicale: du 2D au 3D, les problèmes particuliers posés par la reconstruction tomographique en tomographie par émission de positons

Abstract

1917: Radon shows that a function can, be recontructed from its projections. For 60 years, the implementation of this theory to analogue data is a failure because the measurement noise is drastically amplified. 1970 : Hounsifeld applies Radon's theory, to digital data and builds the first x-ray CT scanner. His approach is generalized to many imaging… (More)
