3D registration of MR and X-ray spine images using an articulated model
(2012-07)Présentation: Cet article a été publié dans le journal : Computerised medical imaging and graphics (CMIG). Le but de cet article est de recaler les vertèbres extraites à partir d’images RM avec des vertèbres extraites à partir d’images RX pour des ... -
Analysis of scoliosis trunk deformities using ICA
(2012-07-02)This paper describes a method for analyzing scoliosis trunk deformities using Independent Component Analysis (ICA). Our hypothesis is that ICA can capture the scoliosis deformities visible on the trunk. Unlike Principal Component Analysis (PCA), ICA ... -
Articulated Model Registration of MRI/X-Ray Spine Data
(Springer Berlin Heidelberg, 2010-06)This paper presents a method based on articulated models for the registration of spine data extracted from multimodal medical images of patients with scoliosis. With the ultimate aim being the development of a complete geometrical model of the torso ... -
Multilevel Analysis of Trunk Surface Measurements for Noninvasive Assessment of Scoliosis Deformities
(2012-08-01)Study Design. Reliability study. Objectives. To assess between-acquisition reliability of new multilevel trunk cross sections measurements, in order to define what is a real change when comparing 2 trunk surface acquisitions of a same patient, before ... -
Multimodal image registration of the scoliotic torso for surgical planning
(2013-12)Background This paper presents a method that registers MRIs acquired in prone position, with surface topography (TP) and X-ray reconstructions acquired in standing position, in order to obtain a 3D representation of a human torso incorporating the ... -
Non invasive classification system of scoliosis curve types using least-squares support vector machines
(Elsevier, 2012-10-01)Objective To determine scoliosis curve types using non invasive surface acquisition, without prior knowledge from X-ray data. Methods Classification of scoliosis deformities according to curve type is used in the clinical management of scoliotic ... -
Noninvasive Clinical Assessment of Trunk Deformities Associated With Scoliosis
(2013-03-07)Besides the spinal deformity, scoliosis modifies notably the general appearance of the trunk resulting in trunk rotation, imbalance, and asymmetries that constitutes patients' major concern. Existing classifications of scoliosis, based on the type of ... -
A novel method for the 3-D reconstruction of scoliotic ribs from frontal and lateral radiographs
(2009-09-29)Among the external manifestations of scoliosis, the rib hump, which is associated with the ribs' deformities and rotations, constitutes the most disturbing aspect of the scoliotic deformity for patients. A personalized 3-D model of the rib cage is ... -
Patient-specific model of a scoliotic torso for surgical planning
(2013-03)A method for the construction of a patient-specific model of a scoliotic torso for surgical planning via inter- patient registration is presented. Magnetic Resonance Images (MRI) of a generic model are registered to surface topography (TP) and X-ray ... -
Prediction of scoliosis curve type based on the analysis of trunk surface topography
(2010-04)Scoliosis treatment strategy is generally chosen according to the severity and type of the spinal curve. Currently, the curve type is determined from X-rays whose acquisition can be harmful for the patient. We propose in this paper a system that can ... -
Scoliosis curve type classification from 3D trunk image
(2012-02-23)Adolescent idiopathic scoliosis (AIS) is a deformity of the spine manifested by asymmetry and deformities of the external surface of the trunk. Classification of scoliosis deformities according to curve type is used to plan management of scoliosis ... -
Scoliosis Follow-Up Using Noninvasive Trunk Surface Acquisition
(2013-03-13)Adolescent idiopathic scoliosis (AIS) is a musculoskeletal pathology. It is a complex spinal curvature in a 3-D space that also affects the appearance of the trunk. The clinical follow-up of AIS is decisive for its management. Currently, the Cobb angle, ... -
Semiautomatic detection of scoliotic rib borders from posteroanterior chest radiographs
(2011-09-15)3-D assessment of scoliotic deformities relies on an accurate 3-D reconstruction of bone structures from biplanar X-rays, which requires a precise detection and matching of anatomical structures in both views. In this paper, we propose a novel semiautomated ... -
Towards Non Invasive Diagnosis of Scoliosis Using Semi-supervised Learning Approach
(Springer Berlin Heidelberg, 2010)In this paper, a new methodology for the prediction of scoliosis curve types from non invasive acquisitions of the back surface of the trunk is proposed. One hundred and fifty-nine scoliosis patients had their back surface acquired in 3D using an optical ...
