Medical sectional imaging using X-ray computer tomography, nuclear spin tomography, etc., whereby an object function is determined using multiple projections with an iterative reconstruction algorithm

摘要

Method for determining an object function from a number of images acquired from different projection angles using an iterative reconstruction algorithm in which an iteration cycle involves determination of a projection, determination or projection correction information, determination of an approximation image and determination of a new projection based on intersection behavior. The preceding steps are repeated as necessary. The invention also relates to a corresponding system and computer program product.
