A record $70 billion of private and public capital poured into life sciences-related companies in North America in 2020, a 93% increase from the previous record of $36 billion received in 2018 [1]. This growth has allowed the scientific community to develop less invasive equipment and treatments using electromagnetic radiation. Therefore, it is crucial to understand how these radiations interact with the human body. Since we cannot easily and comfortably measure inside the body, cylindrical or brick-shaped phantoms made of plastic and filled with a fluid that imitates the body tissue properties are used instead. Simulation has become essential not only to avoid costly and time-consuming prototype fabrication and testing, but also to ensure patient safety from medical devices.<\/p>\n<h5><b>Human body representation for electromagnetic analysis<\/b><\/h5>\n<p>One aspect of great importance in electromagnetic field analysis is the definition and representation of the materials of the different tissues in the human body. There are several variants for the definition of the materials. Usually, cylindrical or brick-shaped phantoms that are made of plastic and filled with a fluid that imitates the body tissue properties are used in measurement. This is not very realistic and does not guarantee accurate results. Therefore, the use of electromagnetic analysis through simulations is practically mandatory in procuring more accurate results.<\/p>\n<h5><b>Models available for biomedical simulations <\/b><\/h5>\n<p>Depending on the frequency band to which the models are exposed to, the electromagnetic field can penetrate the human body and affect inner organ tissues. Therefore, a more accurate and more detailed representation of the interior of the human body is necessary.<\/p>\n<p><span style=\"color: #44546a;\"><span style=\"font-size: small;\"><i><span style=\"color: #000000;\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-19667 size-large\" src=\"http:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig1-1-1024x576.webp\" alt=\"\" width=\"1024\" height=\"576\" srcset=\"https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig1-1-1024x576.webp 1024w, https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig1-1-300x169.webp 300w, https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig1-1-768x432.webp 768w, https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig1-1.webp 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>Figure 1: Models and data sets available for biomedical simulations in CST Studio Suite.<\/span><\/i><\/span><\/span><\/p>\n<p>This is the case where other variants such as surface bio models and voxel models are available. Out of these variants, best option is voxel models which are made of elements like 3D pixels or cubes with a certain resolution, or CAD-based models, such as <a href=\"http:\/\/vias3d.live\/solutions\/catia\/\"><span style=\"color: #ff0000;\">CATIA <\/span><\/a>or <span style=\"color: #ff0000;\">SOLIDWORKS <\/span>with solids for each organ.The\u00a0CST Voxel Family\u00a0is a group of eight human model voxel data sets created from eight persons of different gender, age, and stature. Some are based on CT and MRI scans of actual persons and are available at various resolutions. Others are based on the US National Library of Medicine&#8217;s Visible Human Project\u00ae, for which a frozen corpse was dissected and photographed. Additionally, we have different models such as homogeneous poses (Driver, Walking, Phone Right, Arms Down, Arms Front, Body Scanner), CST animals models (a monkey, a goat, and a rat), the\u00a0Specific Anthropomorphic Mannequin\u00a0(SAM)\u00a0head phantom and CATIA hand models.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-19671 size-full\" src=\"http:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig2.webp\" alt=\"\" width=\"1280\" height=\"720\" srcset=\"https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig2.webp 1280w, https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig2-300x169.webp 300w, https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig2-1024x576.webp 1024w, https:\/\/vias3d.live\/wp-content\/uploads\/2023\/02\/fig2-768x432.webp 768w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><br \/>\n<span style=\"color: #44546a;\"><span style=\"font-size: small;\"><i><span style=\"color: #000000;\">Figure 2: Voxel Model definition for a Living Heart in CST Studio Suite.<\/span><\/i><\/span><\/span><\/p>\n<h5><b>Material definitions<\/b><\/h5>\n<p>In addition to the geometric definition, we need to use the material properties which are accurate and validated. <a href=\"http:\/\/vias3d.live\/solutions\/simulia\/cst-studio\/\"><span style=\"color: #ff0000;\">CST Studio Suite <\/span><\/a>material library contains many different human tissue properties with electromagnetic, thermal, and mechanical properties.

Not only does this library include electromagentic properties but temperature-dependent properties like electrical conductivity or blood perfusion co-efficient for Bioheat calculation.<\/p>\n<p>Once we have the model of the human body accurately represented with a good definition of the electrical properties of the tissues, we can perform an analysis and visualization of the electromagnetic fields in a more accurate manner inside the human body.
