“…Efforts have been made to quantify the 3D deformity of the rib cage from medical imaging, for instance with optical methods (Charles, Marcoul, Schaeffer, Canavese, & Diméglio, 2017;Hocquelet et al, 2016), computerized tomography (CT, Aaro & Dahlborn, 1981;Nankali, Torshabi, & Miandoab, 2017) and biplanar radiography (Cheriet, Laporte, Kadoury, Labelle, & Dansereau, 2007;Grenier, Parent, & Cheriet, 2013;Jolivet, Sandoz, Laporte, Mitton, & Skalli, 2010). Radiography has an advantage over CT and optical methods, as it is already performed in the clinical routine of adolescent idiopathic scoliosis (AIS) patients.…”

Methods to reconstruct anatomical structures in 3D are gaining interest in medicine because they give access to quantitative information on the patient's geometry. However, these methods are user-dependent and require a trained operator, which is time consuming and a source of error and unreliability. The aim of this work was to validate a novel method of landmark selection to perform the 3D reconstruction of the rib cage from biplanar calibrated radiographies. The method uses digital painting for digitization of anatomical landmarks (eight ribs midlines, posterior extrema, sternum) to build a first estimate of the 3D ribcage geometry. Twenty scoliotic patients were included (Cobb angle: 43° ± 11°) and their ribcage was reconstructed twice with the proposed method by four trained operators. Measurement reproducibility was similar to previously validated methods. Uncertainty (95% CI) was 2.3° for the rib hump measurement, 9.7 mm and 3.8 mm for maximal antero-posterior and lateral diameter, 395 cm 3 for ribcage volume. The method was qualitatively considered more user-friendly than previous versions, although it still requires a trained operator, and it took approximately 2 minutes of manual digitization. The new method should facilitate diffusion of 3D quantitative analysis of ribcage in clinical routine.

“…Recently, a slot scanning X-ray system (EOS Imaging, Paris, France) has been developed to capture X-ray images using low radiation dose [13,14]. This system also allows 3-D imaging using a special software program named SterEOS ® , by combing anatomical information obtained along two orthogonal planes, The EOS system is relatively expensive for both the device and its operation [15,16]. Its accessibility will therefore not be high in the foreseeable future.…”

This paper presents an automated measurement of spine curvature by using prior knowledge on vertebral anatomical structures in ultrasound volume projection imaging (VPI). This method can be used in scoliosis assessment with free-hand 3-D ultrasound imaging. It is based on the extraction of bony features from VPI images using a newly proposed two-fold thresholding strategy, with information of the symmetric and asymmetric measures obtained from phase congruency. The spinous column profile is detected from the segmented bony regions, and it is further used to extract a curve representing spine profile. The spine curvature is then automatically calculated according to the inflection points along the curve. The algorithm was evaluated on volunteers with the different severity of scoliosis. The results obtained using the newly developed method had a good linear correlation with those by the manual method (r ≥ 0.90, p <; 0.001) and X-ray Cobb's method (r = 0.83, p <; 0.001). The bigger variations observed in the manual measurement also implied that the automatic method is more reliable. The proposed method can be a promising approach for facilitating the applications of 3-D ultrasound imaging in the diagnosis, treatment, and screening of scoliosis.

“…The BIOMOD ™ L system [26][27][28] consists of a mobile optical data acquisition system (high-definition camera, inclinometers, and a structured light projector) that also needs anatomical landmarks in spinous processes as well as the sacral dimples. This method, as ours, evaluates the three planes: frontal, sagittal, and transverse.…”

Idiopathic scoliosis requires a close follow-up while the patient is skeletally immature to detect early progression. Patients who are monitored by radiographs are exposed to high doses of ionizing radiation. The purpose of this study is to evaluate if an optic noninvasive method of back surface topography based on structured light would be clinically useful in the follow-up of young patients with idiopathic scoliosis. This could reduce the number of radiographs made on these children. Thirty-one patients with idiopathic scoliosis were submitted twice to radiograph and our topographic method at intervals of 6 months to 1 year. Three topographical variables were applied horizontal plane deformity index (DHOPI), posterior trunk symmetry index (POTSI), and columnar profile (PC). A statistically significant correlation was found between variations of Cobb angle with DHOPI (r=0.720, p<0.01) and POTSI (r=0.753, p<0.01) during the monitoring period. Hence, this topographic method could be useful in clinical practice as an objective adjuvant tool in routine follow-up of scoliosis.

Patient-specific 3D models created by 3D imaging system or bi-planar imaging coupled with Moiré–Fringe projections: a comparative study of accuracy and reliability on spinal curvatures and vertebral rotation data

Abstract: While a lower accuracy was observed for the evaluation of the axial rotation, bi-planar imaging coupled with Moiré-Fringe projections may be an accurate and reliable tool to perform 3D reconstructions of the spine and pelvis.
