APPARATUS FOR THE PROCESSING OF PERFUSION IMAGES |
摘要 |
<p>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 (2) of a patient. According to the method, projections p i j are generated from a number M of different directions d i and at different times t i j . Moreover, the time-dependent intensity function I(x,t) of the reconstructed volume is approximated by a predetermined model function I*( a (x),t), wherein the unknown parameter vector a (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 p i j in each iteration step.</p> |
