ISO TS 23541-1-2021 pdf free download – Health informatics — Categorial structure for representation of 3D human body position system — Part 1: Bones.
This document describes the high-level concepts required for representation of 3D data in healthinformation systems from a terminological perspective. It is intended to be used in analysing.developing and managing terminologies in HBPS. The use cases include clinical findings, disorders,problem lists and procedures.
Topics considered in the scope of this document:
– description of terminological concepts for representation of 3D data for human body;-establishing of the relationships needed for 3D data in terminological systems;
– use cases.
Topics considered outside the scope of this document:
— 3D data structure, implementation and software functionality.

3.1 General
3.1.1
3 dimensional3D
computer graphics that define an object by its width, length and depthNote 1 to entry: See Figure 1.
3.1.2
3D data element
unit of 3D data for which the definition,identification， representation, and permissible values arespecified by means of a set of attributes
Note 1 to entry: A 3D data element include vertex (a single point that has three-dimensional position and cornerof a 3D model),edge(where two faces meet), face (surface of 3D model defined by vertices and edges) and polygon(straight-sided shapes, defined by vertices and edges).
Note 2 to entry: See Figure 2.
3.1.3
human anatomy
study of structures in the human body and how the body parts are organized,physical substance of thehuman organism
Note 1 to entry: Human anatomy is composed of living cells and extracellular materials and organized intotissues,organs and systems.
3.1.4
anatomical site
formal representation of a sanctioned characteristic composed of the semantic link {HasAnatomicalSite}with an associative relation to the characterizing category including but not limited to <Anatomicalstructure>

3D human body model
3D model (3.2.1) that represents a normal anatomical structureNote 1 to entry: See Figure 2.
Note 2 to entry: A human body model, which defines systems, organs and body regions, is composed of multiple3D models.ISO TS 23541-1 pdf download.
