00925njm 22002777a 4500 dc Maksimov, D. author Finkel Morgenstern, Federico author Dietz, T. author Diehl, S. author Duber, C. author Rebholz, P. author Hesser, J. author Manner, R. author 2004 In this paper we present a method that allows removing bony structures and. calcifications from CT angiography (CTA) data. It relies on two data sets, one with (CA) and one without (NCA) contrast agent. In contrast to current approaches, the algorithm uses local rigid matching of each single object. Therefore, it allows compensating motion of the patient during acquisition. Furthermore, the method uses a highly accurate surface-matching procedure so that local mismatches can be as small as 3 voxels and therefore even arteries near the bone are mostly separated correctly. The overall system requires about 20 minutes on a Pentium 4 2.4 GHz with 1 GByte RAM for a 700 MByte data set (CA+NCA) and is currently used in the clinic for evaluation purposes. 0-7695-2104-5 10.1109/CBMS.2004.1311746 https://hdl.handle.net/20.500.14352/53463 http://dx.doi.org/10.1109/CBMS.2004.1311746 http://ieeexplore.ieee.org An interactive application for removal of bone information in CT-angiography
