“…The figure 1 shows the twelve anatomical voxel models (3 females, 7 males and 2 children) used in this study. From left to right, the figure 1 shows the UK "Norman" model [Dimbylow 1997], the ETRI Korean male [Lee A.K 2006], the Japanese male "Taro" (JM) and female "Hanako" (JF) [Nagaoka et al 2004], the American Zubal model [Zubal et al 1994], the Visible Human (VH) from VH project [Ackerman 1995], the High Definition Reference Korean model (HDRK) [Kim et al 2008], the UK "Naomi" model [Dimbylow 2005a] and the Virtual Family models [Christ et al 2007] composed of two adults, a male "Duke", a female "Ella" and two children: a 11 years old girl "Billie" and a 6 years old boy "Thelonious" . In order to describe the WBSAR with a surrogate model taking into account the morphological data, the first step consists in characterizing these data and their influence.…”

Abstract.In this paper we propose an identification of morphological factors that may impact the Whole Body Specific Absorption Rate (WBSAR). The study is conducted for the case of an exposure to a front plane wave at the 2100MHz frequency carrier. This study is based on the development of different regression models for estimating the WBSAR as a function of morphological factors morphology. For this manner, a database of twelve anatomical human models (phantoms) has been considered. Also, eighteen supplementary phantoms obtained using morphing technique were generated to build the requested relation. The paper presents three models based on external morphological factors like the Body Surface Area (BSA), the Body Mass Index (BMI) or the body mass. These models show good results for families obtained by morphing technique on the estimation of the WBSAR (< 10%) but still less accurate (30%) when applied for different original phantoms. This study stresses the importance of the internal morphological factors such as muscle and fat proportions in the characterization of the WBSAR. The regression models are then improved using internal morphological factors with an estimation error around 10% on the WBSAR. Finally, this study is suited for establishing the statistical distribution of the WBSAR for a given population characterized by its morphology.

“…Male sectioned images of the VHP, CVH, and VK were used in many ways; for example, for creating atlases (Cho, 2009;, browsing software Shin et al, 2011Shin et al, , 2012a, and virtual dissection software (Schiemann et al, 2000;Spitzer & Scherzinger, 2006), and provided the facility of free access to three dimensional (3D) models in PDF files atlases (Shin et al, 2012b;Park et al, 2013). Furthermore, the sectioned images of VK were used that the dose conversion coefficients of radiology were calculated virtually (Kim et al, 2008).…”

SUMMARY:The objective of this research was to present high-quality sectioned images of a whole female body which would be helpful in creating an atlas, virtual dissection, and various applications for medical education and clinical trial. In addition, the authors sought to demonstrate the applicabilities of sectioned images. A female cadaver was ground serially using the cryomacrotome and photographed to make the sectioned images. Structures in the images were segmented to produce segmented images in Photoshop. In the self-developed browsing software, the sectioned and segmented images were stored. Based on the segmented images, surface models were built on commercial software and saved as PDF file. High-quality sectioned images of the female body were taken (intervals, 0.2 mm or 1 mm; pixel size, 0.1 mm; color depth, 48 bit color). In the images obtained, very small and complicated structures could be identified in color of living body. In order to ascertain the applicability of the images, the browsing software including sectioned and segmented images and the PDF file including surface models were produced. The sectioned images and surface models produced during this research will prove to be a useful source for medical software. All data generated is available free of charge.

“…Several whole body [35,36] and partial body [37,38] anatomical models are constructed from acquired images (X-ray, MRI, CT) of healthy volunteers, patients or cadavers. Some full body modeling attempts [39,40] used high resolution RGB cross sectional image of cadavers, to realize the representation of anatomy. Most of the approaches follow either volumetric or surface modeling.…”
