Zurich Med Tech, a sister company of SPEAG, has developed iSEG, a medical image segmentation tool specially designed to construct realistic 3D human or animal models for SEMCAD X from medical image data. iSEG, the most versatile medical image segmentation tool currently available, quickly and easily creates highly detailed 3D human or animal models based on CT and MRI images in standard image formats. The resulting models can be used to study electromagnetic exposure and induced heating in living tissue.
