1.1 This reference radiograph covers a series of test targets suitable for evaluating, quantifying, and documenting performance parameters of the radiographic digitization process or the electronic image reconstruction process, or both. This reference radiograph can be used for visual and electronic analysis of digitization systems. 1.2 This reference radiograph provides a series of test targets to provide a vehicle for the evaluation of spatial resolution, density contrast sensitivity, dynamic range, and spatial linearity, as well as other aspects of a digitization system. The test targets are suitable for evaluating a digitization system with a spatial resolution down to ;1/1000 in. (25 micrometres (µm)), a density contrast sensitivity down to 0.02 optical density (OD), a density range of 0.5 to 4.5 OD, and a film size capacity of 14 in. (355 mm) wide by 17 in. (431 mm) long. 1.3 From time to time, there may be minor changes to the process for manufacturing of the reference adjunct film. These changes could include changes in the films or processing chemistry used, text designation on the film, etc.; however, in all cases, these changes are reviewed by the Illustration Monitoring Subcommittee to ensure that there are no changes to the functional use of the reference image. Therefore, the adjunct reference films remain valid for use with this standard regardless of the date of production or the revision level of the text standard. 1.4 Units—The values stated in inch-pound units are to be regarded as the standard, with the exception of the spatial resolution targets (6.2 and 6.7) which are stated in SI units. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This test method provides instruction for determining the spatial resolution and contrast sensitivity in X-ray and γ-ray computed tomography (CT) volumes. The determination is based on examination of the CT volume of a uniform cylinder of material. The spatial resolution measurement (Modulation Transfer Function) is derived from an image analysis of the sharpness at the edges of the reconstructed cylinder slices. The contrast sensitivity measurement (Contrast Discrimination Function) is derived from an image analysis of the contrast and the statistical noise at the center of the cylinder slices. 1.2 This test method is more quantitative and less susceptible to interpretation than alternative approaches because the required cylinder is easy to fabricate and the analysis easy to perform. 1.3 This test method is not to predict the detectability of specific object features or flaws in a specific application. This is subject of IQI and RQI standards and standard practices. 1.4 This method tests and describes overall CT system performance. Performance tests of systems components such as X-ray tubes, gamma sources, and detectors are covered by separate documents, namely Guide E1000, Practice E2737, and Practice E2002; c.f. 2.1, which should be consulted for further system analysis. 1.5 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

What is BS EN IEC 61223 ‑ 3 ‑ 6 about? BS EN IEC 61223 discusses evaluation and routine testing in medical imaging departments. BS EN IEC 61223 ‑ 3 ‑ 6 applies to the performance of mammographic x-ray equipment when used in mammographic tomosynthesis modes of operation, with respect to image quality and dose. These methods mainly rely on non-invasive measurements that use appropriate test equipment

IEC 60580:2019 is available as IEC 60580:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60580:2019 specifies the performance and testing of Dose Area Product Meters intended to measure Dose Area Product and/or Dose Area Product Rate to which the Patient is exposed during Medical Radiological Examinations. This document is applicable to the following types of Dose Area Product Meters: a) Field-Class Dose Area Product Meters normally used for the measurement of Dose Area Products during Medical Radiological Examinations; b) Reference-Class Dose Area Product Meters normally used for the Calibration of Field-Class Dosimeters. NOTE Reference-Class Dose Area Product Meters can be used as Field-Class Dose Area Product Meters. The object of this document is 1) to establish requirements for a satisfactory level of performance for Dose Area Product Meters, and 2) to standardize the methods for the determination of compliance with this level of performance. Two levels of performance are specified: – a lower level of performance applying to Field-Class Dose Area Product Meters; – a higher level of performance applying to Reference-Class Dose Area Product Meters. IEC 60580:2019 cancels and replaces the second edition published 2000, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) a second class of devices is introduced with tighter uncertainty tolerances; b) this document has been expanded to include detectors other than ionization chambers; c) radiation qualities have been updated to the new definitions according to IEC 61267; d) a requirement on the linearity of the dose area product rate measurement was added; e) changed chamber light transmission requirement from 70 % to 60 %.

IEC 61223-3-6:2020 applies to the performance of MAMMOGRAPHIC X-RAY EQUIPMENT when used in MAMMOGRAPHIC TOMOSYNTHESIS modes of operation, with respect to image quality and dose. Excluded from the scope of this document are: - MAMMOGRAPHIC X-RAY EQUIPMENT modes of operation other than MAMMOGRAPHIC TOMOSYNTHESIS; - 2D images synthesised from the tomosynthesis images; - reconstructive TOMOGRAPHY other than MAMMOGRAPHIC TOMOSYNTHESIS; - CT SCANNERS covered by IEC 61223-3-5. IEC 61223-3-6:2020 defines a) the essential parameters which describe the acceptability criteria of MAMMOGRAPHIC TOMOSYNTHESIS modes of operation of MAMMOGRAPHIC X-RAY EQUIPMENT with regard to image quality and dose, b) the methods of testing whether measured quantities related to those parameters comply with specified tolerances, and c) CONSTANCY TEST frequency when required. This document is intended to be applied along with the acceptability criteria included in IEC 61223-3-2 or equivalent protocol for 2D mammography which are also relevant for MAMMOGRAPHIC TOMOSYNTHESIS modes of operation. These methods mainly rely on non-invasive measurements that use appropriate test equipment and are performed during or after the installation. Signed statements covering steps in the installation procedure can be used as part of the ACCEPTANCE TEST. Tests required by a higher level of compliance take precedence over similar tests with a lower level of compliance. When the results of the ACCEPTANCE TEST are in compliance with the expected values, the BASELINE VALUES for the subsequent CONSTANCY TESTS are established.
