Prediction of the rib cage volume and thorax density from anthropometric data.
Communication avec acte
Rib cage volume and thorax density are useful both for clinical issues (Sverzellati et al. 2013) and for multi-segmental body modeling. In the latter case mean density is generally assumed, using data from Dempster et al (Dempster 1955), which could be over-evaluated due to the lack of consideration of lung density. Bi-planar X-Ray system (Dubousset et al. 2010) combined with 3D reconstruction allows to get both the rib cage and the external body shape. The aim of this study is to estimate the rib cage volume compared to the thorax volume and to propose a refined thorax density estimation.

A 3D reconstruction method of the body envelope from biplanar X-rays: Evaluation of its accuracy and reliability Article dans une revue avec comité de lectureNÉROT, Agathe; CHOISNE, Julie; AMABILE, Célia; TRAVERT, Christophe; PILLET, Hélène; WANG, Xuguang; SKALLI, Wafa (Elsevier, 2015)The aim of this study was to propose a novel method for reconstructing the external body envelope from the low dose biplanar X-rays of a person. The 3D body envelope was obtained by deforming a template to match the surface ...
Determination of a new uniform thorax density representative of the living population from 3D external body shape modeling. Article dans une revue avec comité de lectureAMABILE, Célia; CHOISNE, Julie; NÉROT, Agathe; PILLET, Hélène; SKALLI, Wafa (Elsevier, 2016)Body segment parameters (BSP) for each body's segment are needed for biomechanical analysis. To provide population-speciﬁc BSP, precise estimation of body's segments volume and density are needed. Widely used uniform ...
Article dans une revue avec comité de lectureAMABILE, Célia; NÉROT, Agathe; CHOISNE, Julie; PILLET, Hélène; LAFAGE, Virginie; SKALLI, Wafa (Taylor & Francis, 2015)Sagittal malalignment is associated with increased disability and can lead to postural troubles. The latter is often the result of an inadequate weight distribution on the spine and trigger compensatory mechanisms. No study ...
Article dans une revue avec comité de lectureNÉROT, Agathe; WANG, Xuguang; PILLET, Hélène; SKALLI, Wafa (Taylor & Francis, 2015)Human external shape model is becoming easily available using scanning technology, stereophotogram- metry, or Microsoft Kinect systems. However locating the internal skeleton from the external shape remains a challenging ...
