Artifacts in spiral CT protocols: The importance of the spatial reconstruction
(2009)Purpose: This study recorded and analysed streak and motion artifacts in spiral CT examinations and evaluated the elimination and minimization of them by the use of segmental reconstruction with and without alterations of ...

Biphasic modeling of brain tumor biomechanics and response to radiation treatment
(2016)Biomechanical forces are central in tumor progression and response to treatment. This becomes more important in brain cancers where tumors are surrounded by tissues with different mechanical properties. Existing mathematical ...

Multiscale AM-FM image reconstructions based on elastic net regression and Gabor filterbanks
(IEEE Computer Society, 2013)The paper proposes the use of elastic net regression for reconstructing images from AM-FM components. Current AM-FM reconstruction methods are based on Dominant Component Analysis (DCA), multi-scale DCA, and Channel Component ...

Shadow volume BSP trees for computation of shadows in dynamic scenes
(ACM, 1995)This paper presents an algorithm for shadow calculation in dynamic polyhedral scenes illuminated by point light sources. It is based on a modification of Shadow Volume Binary Space Partition trees, to allow these be ...

Three-dimensional image reconstruction using the PF/MFS technique
(2009)We propose a geometric modeling method in R3 based on the so-called potential field (PF) modeling technique. The method is a new technique for surface reconstruction from a data set of scattered points taken on a surface. ...
