The CAESAR (Civilian American and European Surface Anthropometry Resource) project completed in 2002 has collected 3D scans of over 5000 subjects. We have created a 3D interface, the NIST CAESAR Viewer (NCV), utilizing the Virtual Reality Modeling Language (VRML) to provide 3D access via the Web. In addition to simply viewing the 3D scans we have augmented the display of the body with interacti...

Using 2D contour sketches as input is an attractive solution for easing the creation of 3D models. This paper tackles the problem of creating 3D models of animals from a single, side-view sketch. We use the a priori assumptions of smoothness and structural symmetry of the animal about the sagittal plane to inform the 3D reconstruction. Our contributions include methods for identifying and infer...

The article proposes a real-time technique for visualizing tongue motion driven by ultrasound image sequences. Local feature description is used to follow characteristic speckle patterns in a set of mid-sagittal contour points in an ultrasound image sequence, which are then used as markers for describing movements of the tongue. A 3D tongue model is subsequently driven by the motion data extrac...

Magnetic Resonance Imaging (MRI) exams suffer from undesirable structure replicating and overlapping effects on certain acquisition settings. These are called Spatial Aliasing Artefacts (SAA) and their presence interferes with the segmentation of other anatomical structures. This paper addresses the segmentation of the SAA in T1-weighted MRI image sets, in order to effectively remove their infl...

Background The goals of Scoliosis Specific Schroth Physiotherapy (SSSPT) are to restore muscle balance, reshape the rib cage and reduce the rib hump to improve the esthetic of the patient, to increase the breathing areas and vital capacity, to reduce the Cobb angles, and to avoid spinal fusion surgery. Measuring the Cobb angles on P-A radiographs, assessing the sagittal profile on lateral radio...

We present the first prototype of a new optoelectronic instrument for the combined real-time measurement of the tongue contour in the mid-sagittal plane, the contact pattern between the tongue and the palate, and the position of the lips. The instrument consists of a thin acrylic pseudopalate with embedded contact sensors, as for electropalatography, and optical distance sensors to measure tong...

To build a personal computer based interactive musculoskeletal anatomic atlas using Visible Man data set, we developed a semi-automated segmentation program by using an intelligent scissors approach and a shape-based interpolation. Manual contour extractions at 3mm slice intervals and shape-based interpolations of inter-slices of the musculoskeletal structures of the lower extremity were carrie...

Adolescent idiopathic scoliosis in 152 patients was treated by Luque L-rod instrumentation and early mobilisation without external support. This series was compared with a matched group of 156 patients treated by Harrington instrumentation and immobilised in an underarm jacket for nine months. All the operations in both groups were performed by one surgeon and the patients were followed prospec...

In order to evaluate the lateral shape contour of the Neanderthal cranium, the mid-sagittal profiles (glabella-opisthocranion) in adult and subadult Neanderthal remains were examined and compared with those of other specimens of fossil Homo. Size normalized boundaries were digitally acquired as ordered series of coordinates; the series of the distances from the glabella opisthocranion axis, was...
