IEEE Std 3333.2.1 pdf free download.Three-Dimensional (3D) Medical Modeling.
1.1 Background
Medical images from hospitals consist of a two-dimensional (2D) dataset and provide human body information as a slice, but the human body has three-dimensional (3D) morphology. If we should simulate this 3D morphology, we might be able to obtain more information about the body as well as contribute in the clinical environment to both treatment and surgical outcomes. Our objective is to generate 3D medical data from 2D images. Although doctors expend a great deal of time and effort in this process, the resultant 3D data is different in each institute. This protocol, therefore, provides standard, easy, and accurate 3D data for clinical fields and even for industrial markets. A standardized file with 3D medical data, considering each data character from a different place, will yield steady quality visualization. Therefore, this standard suggests standardized data including 3D processing techniques. A more realistic 3D model and a basic model are shown in Figure 1.
1.2 Scope
This standard includes volume- and surface-rendering techniques for 3D reconstruction from 2D medical images. Also, it contains a texturing method of 3D medical data for realistic visualization. Standardization related to medical services includes medical equipment utilizing 2D images, 3D medical data, and contents for diagnosis and treatment. Standardization of medial contents, software, and hardware will enhance safety, economy, and quality of 3D medical services. (see Figure 2).
1.3 Purpose
Medical images from hospitals consist of a 2D dataset, providing information from the human body as sectioned slices. The human body has morphological structure in 3D space. Therefore, to recognize human organs, the 3D reconstruction process is necessary to be reformed using 2D slices. After this, the precise position and shape of organs can be identified.
Medical 3D volume imaging is based on unprocessed 3D medical data that contains a variety of medical information. It determines guidelines, standards of medical 3D technology, and the 3D volume image’s safety and quality. This standard describes the generation and practical use of medical 3D modeling for diagnostic and therapeutic applications.
