T/ZMDS 10027-2026 Determination method of the Dynamic Flying focal spot from a rotating anode X-ray tube assemblies for medical diagnosis

Scope

This document specifies the relevant terms, measurement methods, and calculation and judgment of measurement results for the flying focus of medical diagnostic rotating anode X-ray tube assemblies and X-ray tubes (hereinafter referred to as X-ray tube assemblies). This document is applicable to the flying focus measurement methods of X-ray tube assemblies with an operating voltage not exceeding 150 kV (including 150 kV) that have a flying focus function. While determining whether the measurement methods and test requirements adopted in this document are met, the specified characteristics of the focus and the testing methods are also described, as well as the materials (dynamic flat-panel detectors), equipment (such as computed tomography (CT) devices), and instruments (such as focus measurement devices) used to achieve these characteristics. The flying focus technology in computed tomography (CT). By changing the focus position under the action of electric and magnetic fields, the spatial resolution is improved under the same conditions of detector and gantry rotation speed. This document specifies the definition of the flying focus of CT X-ray tube assemblies, focus size, focus offset, measurement methods, etc. The main content is composed of an introduction, a preface, and a main body, as well as appendices. The introduction and preface are explanations of the basic situation of this standard. The main body consists of seven parts, namely scope, normative reference documents, terms and definitions, abbreviations, test conditions and instruments and equipment, test methods, and parameter annotation of the flying focus. The appendices consist of three informative appendices.
