Abstract
The invention relates to an apparatus and a method for the reconstruction of time-dependent cross-sectional images and may be applied for example in perfusion imaging in the vessel system () of a patient. According to the method, projections pare generated from a number M of different directions dand at different times t. Moreover, the time-dependent intensity function I(x,t) of the reconstructed volume is approximated by a predetermined model function I*((x),t), wherein the unknown parameter vector(x) is estimated for each voxel x. This estimation may be done using the update functions of known reconstruction algorithms like ART for at least N projections pin each iteration step.
