Atherosclerotic carotid plaque segmentation
(2004)Atherosclerosis is the major cause of heart attack and stroke in the western world. In this paper we present a computerized method for segmenting the athrerosclerotic carotid plaque from ultrasound images. The method uses ...

Automatic Landmark Location for Analysis of Cardiac MRI Images
(2012)This paper addresses the problem of automatic location of landmarks used for the analysis of MRI cardiac images. Typically the landmarks of shapes in MRI images are located manually which is a time consuming process requiring ...

Article
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 ...

Bone pain in thalassaemia: assessment of DEXA and MRI findings
(1998)An increasing number of adult thalassaemics have been complaining of aches and pains of varying degrees of severity. In a minority the pains are debilitating and there is stiffness in movement. This study is an attempt to ...

Brain MR image normalization in texture analysis of multiple sclerosis
(2009)A problem that occurs in texture analysis and quantitative analysis of magnetic resonance imaging (MRI), is that the extracted results are not comparable between consecutive or repeated scans or, within the same scan, ...

Effect of posture change on the geometric features of the healthy carotid bifurcation
(2011)Segmented cross-sectional MRI images were used to construct 3-D virtual models of the carotid bifurcation in ten healthy volunteers. Geometric features, such as bifurcation angle, internal carotid artery (ICA) angle, ...

Article
Impact of head rotation on the individualized common carotid flow and carotid bifurcation hemodynamics
(2014)This paper aims at evaluating the changes that head rotation poses on morphological and flow characteristics of the carotid bifurcation (CB) and on the distribution of parameters that are regarded as important in atherosclerosis ...
