“…Buffa et al [11] reported that a 3D scan technique yielded volume data of an upper arm that were reliable and valid. In that study, volume error measures of an arm were between 1.4% and 2.6% -which is similar to the error observations we made.…”

“…In our study, scans were made by having the researcher freely move the scanner around the object of interest. Buffa et al [11] constructed a device that controlled the movement of the scanner about the object. It seems that the error we observed was reasonable especially given the lack of control of movement of the scanner.…”

Background: Commercial 3 Dimension (3D) scanners are relatively new to anthropometry. The purpose of this study was to explore ability of using a 3D imaging instrument to measure body volume with and without wearing a wetsuit. Three experiments were conducted to achieve this purpose: (1) to determine if the 3D imaging instrument could accurately measure volume of static objects; (2) to determine the resolution of accuracy of measuring volume of static objects; and (3) to compare whole-body volume of wearing a wetsuit using 3D imaging as well as another body volume measure (air displacement technique). Methods: Three experiments were performed: (1) measurement of volume of a mannequin head and a box using a 3D scanner, water displacement (for mannequin head), and dimension measurements (for box) techniques for determining volume, (2) volume measurements of 1, 2, and 3 layers of neoprene to assess the resolution capabilities of the 3D scanner, and (3) body volume with and without wearing a wetsuit using a 3D scanner and BodPod (air displacement instrument). Results: (1) Mannequin head volume using the 3D scanner was 1.46% greater than a water displacement technique; the box volume from scanning was significantly greater than volume calculated by measuring dimensions of a box. (2) The volume of a single layer of neoprene was 25.3% less with scanning than the criterion; the volume of two layers was 27.2% less than the criterion; the volume of three layers was not significantly different from the criterion. (3) Body volume was not influenced by the interaction of wetsuit and device; body volume was on average 5% greater with wetsuit than without regardless of instrument. Conclusions: We demonstrated that body volume as measured by a 3D scanner increased when a wetsuit was worn.

“…We investigated the consistency of measurements taken using 3-D scanning with those taken using water displacement in this study. Although a very high correlation between the conventional method and 3-D scanning method was observed, the %LOA was -4% to 7%, compared to a %LOA of water displacement of −2.6% to 1.4% [ 22 ]. While the 3-D scanning method was less accurate than the water displacement method, the error caused by the 3-D scanning method is considered to be clinically acceptable given the advantages over water displacement.…”

Non-invasive volumetric analysis of asymptomatic hands using a 3-D scanner

et al. 2017

Hand swelling is one of the symptoms often seen in practice, but none of the available morphometric methods can quickly and efficiently quantify hand volume in an objective manner, and the current gold-standard volume measurement requires immersion in water, which can be difficult to use. Therefore, we aimed to analyze the accuracy of using 3-dimensional (3-D) scanning to measure hand volume. First, we compared the hand volume calculated using the 3-D scanner to that calculated from the conventional method among 109 volunteers to determine the reliability of 3-D measurements. We defined the beginning of the hand as the distal wrist crease, and 3-D forms of the hands were captured by the 3-D scanning system. Second, 238 volunteers (87 men, 151 women) with no disease or history of hand surgery underwent 3-D scanning. Data collected included age, height, weight, and shoe size. The wrist circumference (WC) and the distance between distal wrist crease and tip of middle finger (DDT) were measured. Statistical analyses were performed using linear regression to investigate the relationship between the hand volume and these parameters. In the first study, a significantly strong positive correlation was observed [R = 0.98] between the hand volume calculated via 3-D scanning and that calculated via the conventional method. In the second study, no significant differences between the volumes, WC or DDT of right and left hands were found. The correlations of hand volume with weight, WC, and DDT were strong. We created a formula to predict the hand volume using these parameters; these variables explained approximately 80% of the predicted volume. We confirmed that the new 3-D scanning method, which is performed without touching the hand and can record the form of the hand, yields an accurate volumetric analysis of an asymptomatic hand.

“…However, CT and laser scanning require expensive equipment, intricate workflows, and trained operators, and therefore are resourceintensive [3,5,6]. Structured light scanning could be implemented through low-cost hardware and software, but its accuracy is not sufficient for skeletal anthropology applications [7,8].…”

Background Ultra close-range digital photogrammetry (UCR-DP) is emerging as a robust technique for 3D model generation and represents a convenient and low-cost solution for rapid data acquisition in virtual anthropology. Objectives This systematic review aims to analyse applications, technical implementation, and performance of UCR-DP in skeletal anthropology. Methods The PRISMA guidelines were applied to the study. The bibliographic search was performed on March 1 st , 2019 using Scopus and MEDLINE databases to retrieve peer-reviewed studies accessible in English full-text. The authors worked independently to select the articles meeting inclusion criteria, upon discussion. Studies underwent to quantitative and qualitative syntheses. Results Twenty-six studies were selected. The majority appeared in 2016 or after and were focused on methodological aspects; the applications mainly dealt with the documentation of skeletal findings and the identification or comparison of anatomical features and trauma. Most authors used commercial software packages, and an offline approach. Research is still quite heterogeneous concerning methods, terminology and quality of results, and proper validation is still lacking. Conclusions UCR-DP has great potential in skeletal anthropology, with many significant advantages: versatility in terms of application range and technical implementation, scalability, and photorealistic restitution. Validation of the technique, and the application of the cloud-based approach, with its reduced requirements relating to hardware, labour, time, and cost, could further facilitate the sharing of large collections for research and communication purposes.
