“…The method for rapid generation of a subject‐specific human model by mesh morphing has been reported in our previous studies . First, with a given target age, sex, stature, and BMI, the skeleton (including rib cage, femur, and pelvis) and external body shape geometries were predicted by the statistical geometry models developed previously .…”

“…They found that subject‐specific femur models produced more accurate impact responses than a single midsize male model or scaled models using traditional scaling techniques. Hwang et al developed a method to rapidly morph a baseline whole‐body human model to diverse human characteristics and evaluated the morphed models against two PMHS in side impacts . However, these two PMHS were both normal weight (BMI < 30 kg/m 2 ).…”

“…The consortium is working on the development of both male and female CHPs of different heights 4 in both standing and sitting positions [103] [104] [105]. The Total Human Model for Safety (THUMS) is a family of models developed by Toyota that include a 5 th percentile adult female, 50 th and 95 th percentile adult males, and 3, 6, and 10 year-old children [106] [107].…”

Over the past decades, significant improvements have been made in the field of computational human phantoms (CHPs) and their applications in biomedical engineering. Their sophistication has dramatically increased. The very first CHPs were composed of simple geometric volumes, e.g., cylinders and spheres, while current CHPs have a high resolution, cover a substantial range of the patient population, have high anatomical accuracy, are poseable, morphable, and are augmented with various details to perform functionalized computations. Advances in imaging techniques and semi-automated segmentation tools allow fast and personalized development of CHPs. These advances open the door to quickly develop personalized CHPs, inherently including the disease of the patient. Because many of these CHPs are increasingly providing data for regulatory submissions of various medical devices, the validity, anatomical accuracy, and availability to cover the entire patient population is of utmost importance. The article is organized into two main sections: the first section reviews the different modeling techniques used to create CHPs, whereas the second section discusses various applications of CHPs in biomedical engineering. Each topic gives an overview, a brief history, recent developments, and an outlook into the future.

“…The scaling procedure implements a reference model and updates its global dimensions to describe an average representative of the population group with the given anthropometry [6][7][8]. Whilst scaling changes only the global dimensions (anthropometry, mass, and stiffness) based on the general anthropometric parameters [6,7], personalization updates the local geometrical and biomechanical details of the particular human body segments [9][10][11] and so leads to a particular subject-specific model. In general, geometrically, the reference model is usually described by a cloud of nodes connected to elements creating the surface mesh.…”

Personalization of a Human Body Model Using Subject-Specific Dimensions for Designing Clothing Patterns

Virtual human body models contribute to designing safe and user-friendly products through virtual prototyping. Anthropometric biomechanical models address different physiques using average dimensions. In designing, e.g., personal protective equipment, orthopedic tools, or vehicle safety systems, biomechanical models with the correct geometry and shape shall play a role. The presented study shows the variations of subject-specific anthropometric dimensions from the average of the different population groups in the Czech Republic and China as a background for the need for personalized human body models. The study measures a set of dimensions used to design clothing patterns of Czech children, Czech adolescents, Czech adults, and Chinese adults and compares them to the corresponding age average, which is represented by a scaled anthropometric human body model. The cumulative variation of the dimensions used to design the clothing patterns increases the further the population group is from the average. It is smallest for the Czech adults at 7.54 ± 6.63%; Czech adolescents report 7.93 ± 6.25%; Czech children differ be 9.52 ± 6.08%. Chinese adults report 10.86 ± 11.11%. The variations from the average of the particular dimensions used to design clothing patterns prove the necessity of having personalized subject-specific models. The measured dimensions used to design the clothing patterns serve as the personalization of particular body segments and lead to a subject-specific virtual model. The developed personalization algorithm results in the continuous body surface desired for contact applications for assessing body behavior and injury risk under impact loading.
