YY/T 0458-2014Technical requirements for ultrasonically blood-mimicking Doppler phantom (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

Instead of the standard YY/T 0458-2003 "imitation blood flow Doppler ultrasound phantom technical requirements." Compared with YY/T 0458-2003, mainly technical changes include.

--- Original based on international standards, on the basis of repeated scrutiny and research on the translation has been modified, the statement more accurate;

--- International standard referenced in the original standard, after 2003 who have converted to domestic standards, references to national standards;

--- Remove ambiguity and a small amount of meaning in the academic, industries no realistic terms, definitions entries;

--- According to the actual technology, product development and clinical application of the progress, the original international standard text to the Doppler frequency of the main line of thinking To the main line to the flow velocity;

--- An increase of some has been widely used in academic, industrial and clinical practice, the international standard texts were not included in the terms, definitions entry;

--- Original reference to international standards, supplemented with the symbol table and technical specifications marked sections and some illustrative text.

This revised standard adopts IEC 61685:2001 "ultrasonic blood flow measuring blood flow phantom." This standard and IEC 61685:2001 technical differences and the reasons are as follows.

--- In accordance with our practice, the original title of the standard three-stage structure to a "technical requirements for imitate Doppler blood flow phantom." --- According to the US Institute of Ultrasound in Medicine (AIUM) and the definition of strict international standard IEC 61206:1993 in reference to the standard Faithfully object called a "phantom." Content --- original standard relates to methods of measuring the acoustic properties of the medium, the Department cited papers or short text to explain, but our country has developed There are technical standards; normative references, some IEC standard had been converted to our standards, the situation above activities are changed To refer to our standards. But imitation imitation blood and tissue material back scattering coefficient measurement method, internationally still under study, is not formed A standardized document, it is still relevant reference works listed in the references.

--- Clutter clutter is medical ultrasound Doppler technology is a very important term appears more than once in the original standard has not given fixed Meaning, especially to the income and were defined.

--- Original proposed standards identified by technical indicators, some content is still under study and explore, we can not put into practical use, leaving only the conversion With existing international commodity random file on the same section.

--- Original standard Appendix D is the drafting of the research experiment content, total income and the necessity of not causing lengthy document, especially to Jane Short text description, those interested can read the original.

1 Scope

This standard specifies the technical requirements and methods of measurement of blood flow Doppler ultrasound phantom imitation.

This standard applies to the ultra ultrasound tissue mimicking material, embedded buried pipes and materials for steady state flow in the pipeline imitation blood composition Acoustic Doppler blood flow phantom imitation (hereinafter referred to as imitation blood flow phantom), the device is mainly used for performance testing Doppler ultrasound diagnostic equipment and Evaluation.
