[Poster] 4th European Molecular Imaging Meeting, Barcelona, Spain, May 27 - 30, 2009Preliminary results are presented of a 4d reconstruction algorithm for dynamic
contrast enhanced CT, in a micro-CT based on cone beam geometry. The method is based on
modelling the spatial and temporal distribution of the contrast inside the field of view. The use of
non-uniform time sampling with b-splines yielded smooth time-activity curves that captured the
relatively fast rise and fall of contrast in the aorta, as well as the uptake and retention of contrast in
the kidneysThis work is supported by Ministerio de Ciencia e innovación (TeC2008-06715-C02-01 and TeC2007-64731/TCM), Ministerio de industria (CdTeaM, Programa CeniT), and the reCaVa-reTiC network.Publicad
