Evaluation and routine testing in medical imaging departments Part 3-2.Mammographic X-ray equipment Imaging performance acceptance test1 ScopeThis document is applicable to the effectiveness evaluation of mammography X-ray equipment in terms of image quality and dose, and also covers equipment safety aspects. content. This document applies to mammography X-ray equipment (hereinafter referred to as "mammography X-ray equipment") and mammography stereotactic devices. When the X-ray image receptor is not part of the mammography equipment, the tests described in this document shall ensure that the X-ray image receptor is not part of the mammography equipment. The quality and performance of X-ray image receptors, including X-ray photographic film (hereinafter referred to as "film"), intensifying screens, X-ray photographic cassettes (hereinafter referred to as "dark box"), storage phosphor plate (hereinafter referred to as "IP plate") and auxiliary equipment, such as film processor or storage phosphor plate reading device (hereinafter referred to as "IP plate") (abbreviated as "CR"), image display devices and hard copy cameras. Note. For the description of IP board and CR, see 3.2 and 3.1 of YY/T 0794-2022. For tests on cassettes and intensifying screens in this document, see ISO 4090.For tests on sensitivity and contrast of screen-film image receptors, see ISO 4090. ISO 9236-3. The measurements described in this document provide data for the calculation of mean glandular doses. When the result of the acceptance test meets the expected value, this value can be used as the benchmark value for subsequent stability tests. This document defines. a) basic parameters of the performance of the above-mentioned mammography equipment in terms of image quality and dose; and b) Methods for checking whether the measurement results related to these parameters comply with the specified deviations. These methods are mainly based on non-intrusive measurements using appropriate test equipment and are performed during or after installation. A signed declarative document containing the steps of this document can be used as part of the acceptance test. Take precedence over similar tests in lower-level conformance requirements. This principle is described in 4.1. This document does not specify limits or deviations for the parameters to be measured. Difficulties may arise in identifying the responsible party for the acceptance test when changes are made to the screen-film combination, film developer, or CR. There are a number of reasons for this. First, the image receptor manufacturer and the X-ray equipment manufacturer may be different. Second, the image receptor manufacturer may be different. Changes in receivers or film processing chemicals may alter system performance. When these situations occur, it is important to perform acceptance testing. When changes occur that may alter system performance, the system integrator (i.e., the party responsible for handling the changes) discusses the changes with the X-ray equipment manufacturer. It is important to understand the impact of variability so that the latter can adjust the imaging system if necessary. Acceptance testing of mammography equipment requires general skills in medical physics. The execution of the tests is governed by relevant regulations (e.g. Decisions (including agreements, regulations, and laws).2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.
