Computed radiography (CR) has many advantages compared with conventional radiographs, especially in image processing. Although CR is being used in chest radiography and mammography, it has not been applied to spine imaging. The purposes of this study were to formulate a set of new CR processing parameters and to test whether the resultant whole-spine radiographs visualized the spine more clearl...

Spine is the most essential part of human body. Vertebrae and intervertebral discs are important parts of Spine. The Inter vertebral disc (IVD) is a complex and load bearing structure. IVD undergoes a process of change with age and leads to failures. This paper presents a novel model to detect IVD failures using Magnetic Resonance (MR) images. The proposed method makes use of Vertebrae Statisti...

INTRODUCTION Orthodontic diagnosis includes the interpretation of the relations between the craniofacial and cervical system, given the potential impact of the irregularities from one system to another. OBJECTIVE The aim of this study was to examine morphological characteristics of the cervical spine, depending on the parameters of the vertical craniofacial growth and gender in adult subjects...

The robotic lumbar spine (RLS) is a 15 degree-of-freedom, fully cable-actuated robotic lumbar spine which can mimic in vivo human lumbar spine movements to provide better hands-on training for medical students. The design incorporates five active lumbar vertebrae and the sacrum, with dimensions of an average adult human spine. It is actuated by 20 cables connected to electric motors. Every vert...

Precise vertebrae segmentation is essential for the image-related analysis of spine pathologies such as vertebral compression fractures and other abnormalities, well clinical diagnostic treatment surgical planning. An automatic objective system vertebra required, but its development likely to run into difficulties low accuracy requirement prior knowledge or human intervention. Recently, methods...

Inaccurate identification of vertebral levels is the main cause of wrong-site spine surgery which is performed by nearly half of the spine surgeons. Unusual anatomy and failure to verify the surgical level on radiographs have been commonly reported. We aimed at investigating the variations in vertebral number in adolescent idiopathic scoliosis (AIS) patients and thus to raise awareness of the p...

Robust localisation and identification of vertebrae is an essential part of automated spine analysis. The contribution of this work to the task is two-fold: (1) Inspired by the human expert, we hypothesise that a sagittal and coronal reformation of the spine contain sufficient information for labelling the vertebrae. Thereby, we propose a butterflyshaped network architecture (termed Btrfly Net)...

Normally the 7th cervical vertebra (C7) has a long non-bifid spine. A bifid spine is a feature of typical cervical vertebrae such as C3--C6. In contrast to past studies, which have described a bifid spine in the C3--C6 cervical vertebrae, this study is a report on the presence of a duplicated spinous process in the C7 vertebra with an intervening space. The presence of such anomalies may be ass...

Knowledge about the vertebrae is a valuable source of information for several annotation tasks. In recent years, the research community spent a considerable effort for detecting, segmenting and analyzing the vertebrae and the spine in various image modalities like CT or MR. Most of these methods rely on prior knowledge like the location of the vertebrae or other initial information like the man...
