ABSTRACT
Recent progress in computer speed and medical imaging has made possible the development of a new family of anthropomorphic models, based on a volume elements (voxels) approach to phantom design. Such phantoms can represent details of the anatomical structures of the human body more realistically. Tomographic images (CT or MRI) contain the basic information for the construction of voxel-based phantoms. Use of voxel-based phantoms has its most significant application in the planning of individual patients therapy. To be implemented, results must be obtained in a reasonably short period of time. The segmentation of organs and tissues is a critical step in this process. This article presents a new approach in the construction of voxel-based phantoms that was implemented to simplify the segmentation process of organs and tissues, reducing the time used in this procedure. A voxel-based head and neck phantom, called MCvoxEL, was built using this new approach. The volumes and masses of the segmented organs and tissues were compared with data published by other investigators.
