Esthetic evaluation of facial cheek volume: A study using 3D stereophotogrammetry, J Feng, HY Yu, YJ Yin, YQ Yan, Z Wang, D Bai, XL Han.

Date: October 2018. Source: The Angle Orthodontist. Objective: To investigate the influence of cheek volume on facial esthetics judged by orthodontists and non-specialists. Materials and Methods: A 25-year-old female’s natural and smiling face was captured by 3D stereophotogrammetry. Cheek volume of the 3dMD image was altered to different degrees three-dimensionally. For the natural and smiling…

Regression of cephalic index following endoscopic repair of sagittal synostosis. NA Pickersgill, GB Skolnick, SD Naidoo, MD Smyth, KB Patel.

Date: October 2018. Source: Journal of Neurosurgery: Pediatrics [Online Before Print]. Objective: Metrics used to quantify preoperative severity and postoperative outcomes for patients with sagittal synostosis include cephalic index (CI), the well-known standard, and the recently described adjusted cephalic index (aCI), which accounts for altered euryon location. This study tracks the time course of these…

Applications and limitations of using patient-specific 3D printed molds in autologous breast reconstruction. S Hummelink, AC Verhulst, TJJ Maal, DJO Ulrich.

Date: October 2018. Source: European Journal of Plastic Surgery, Volume 41, Issue 5, pp 571–576. Background: Over the last years, several techniques have been proposed to improve the outcome of autologous breast reconstruction procedures. One of these innovations describes patient-specific, three-dimensional (3D) printed breast molds for intraoperative use based on 3D stereophotogrammetry. In this article,…

Effect of surrogate design on the measured stiffness of snowboarding wrist protectors. C Adams, D James, T Senior, T Allen, N Hamilton.

Date: September 2018. Source: Sports Engineering, Volume 21, Issue 3, pp 217–225. Abstract: In snowboarding, the wrist is the most common injury site, as snowboarders often put their arms out to cushion a fall. This can result in a compressive load through the carpals coupled with wrist hyperextension, leading to ligament sprains or carpal and…

Reconstruction of the oral commissure in patients with unilateral transverse facial cleft. M Tuersunjiang, X Long, Y Fu, J Ke, H He, J Li.

Date: September 2018. Source: British Journal of Oral and Maxillofacial Surgery, Volume 56, Issue 7, pp 621-625. Abstract: The normal commissure is not a simple joint of the upper and lower lip, but a triangular mucosal area. To reconstruct a symmetrical oral commissure in patients with a unilateral transverse facial cleft, we designed composite vermilion…

DeepWrinkles: Accurate and Realistic Clothing Modeling. Zorah Lähner, Daniel Cremers, Tony Tung.

Date: September 2018. Source: 15th European Conference on Computer Vision (ECCV), Munich, Germany. Abstract: We present a novel method to generate accurate and realistic clothing deformation from real data capture. Previous methods for realistic cloth modeling mainly rely on intensive computation of physics-based simulation (with numerous heuristic parameters), while models reconstructed from visual observations typically…

Generating 3D Faces using Convolutional Mesh Autoencoders. A Ranjan, T Bolkart, S Sanyal, MJ Black.

Date: September 2018. Source: 15th European Conference on Computer Vision (ECCV), Munich, Germany, (pp 704-720). Abstract: Learned 3D representations of human faces are useful for computer vision problems such as 3D face tracking and reconstruction from images, as well as graphics applications such as character generation and animation. Traditional models learn a latent representation of…

A scale space approach for exploring structure in spherical data. V Vuollo, L Holmström.

Date: September 2018. Source: Computational Statistics & Data Analysis, Volume 125, pp 57-69. Highlights: • A novel scale space technique for analyzing spherical data is proposed. • Distributions of normal vector directions computed from a 3dMDhead image are analyzed. • A movie is a convenient way to explore the maps included in a SphereSiZer atlas.…

Development of three-dimensional facial expression models using morphing methods for fabricating facial prostheses. A Matsuoka, F Yoshioka, S Ozawa, J Takebe.

Date: September 2018. Source: Journal of Prosthodontic Research. Purpose: It is essential to fabricate a best-fit three-dimensional (3D) facial prosthesis model capable of facial expressions. In order for the facial prosthesis to remain in position, especially around marginal areas subject to movement, a new method of making 3D facial expression models using time-series data allowing…

Non-radiographic severity measurement of pectus excavatum. DP Bliss Jr, NA Vaughan, RM Walk, JA Naiditch, AA Kane, RR Hallac.

Date: September 2018 [Online Before Print]. Source: Journal of Surgical Research, Volume 233, pp 376-380. Background: o avoid the radiation exposure of CT imaging and the expense of CT or MRI studies, we sought to develop a non-radiographic severity measurement of pectus excavatum based on 3D photogrammetric imaging. Methods: Over 28 mo, ten consecutive patient…
