In this paper, recent progress in the field of computational human phantoms (CHPs) and their applications in biomedical engineering is reviewed. The very first CHPs were composed of simple geometric volumes, e.g., cylinders and spheres, while current CHPs are of high resolution, cover a substantial range of the patient population, have high anatomical accuracy, are poseable and morphable, and are augmented with various physical and physiological layers to perform functionalized computations. Advances in imaging techniques and semi-automated segmentation tools allow rapid and personalized development of CHPs. These advances open the door to efficient development of personalized CHPs, including models that feature individualized disease representations. Because many CHP applications increasingly provide data for regulatory submissions concerning various medical devices, the validity, anatomical accuracy, and availability to cover the entire patient population is of utmost importance. This review paper is organized into two main sections: the first section is a review of the different modeling techniques used to create CHPs, whereas the second section is a discussion of various applications of CHPs in biomedical engineering. On each topic, an overview, a brief history, recent developments, and an outlook into the future are provided.
The scientific and technical impact of CHPs be summarized as:
