Ultrasonics - Focusing transducers - Definitions and measurement methods for the transmitted fields

Ultrasonics - Focusing transducers - Definitions and measurement methods for the transmitted fields

This International Standard - provides definitions for the transmitted field characteristics of focusing transducers for applications in medical ultrasound; - relates these definitions to theoretical descriptions, design, and measurement of the transmitted fields of focusing transducers; - gives measurement methods for obtaining defined characteristics of focusing transducers; - specifies beam axis alignment methods appropriate for focusing transducers. This International Standard relates to focusing ultrasonic transducers operating in the frequency range appropriate to medical ultrasound (0,5 MHz to 40 MHz) for both therapeutic and diagnostic applications. It shows how the characteristics of the transmitted field of transducers may be described from the point of view of design, as well as measured by someone with no prior knowledge of the construction details of a particular device. The radiated ultrasound field for a specified excitation is measured by a hydrophone in either a standard test medium (for example, water) or in a given medium. The standard applies only to media where the field behaviour is essentially like that in a fluid (i.e. where the influence of shear waves and elastic anisotropy is small), including soft tissues and tissue-mimicking gels. Any aspects of the field that affect their theoretical description or are important in design are also included. These definitions would have use in scientific communications, system design and description of the performance and safety of systems using these devices.

Ultrasons - Transducteurs focalisants - Définitions et méthodes de mesurage pour les champs transmis

La présente Norme internationale spécifie: - des définitions des caractéristiques du champ transmis de transducteurs focalisants pour des applications ultrasonores médicales; - la relation entre ces définitions et les descriptions théoriques, la conception et le mesurage des champs transmis par des transducteurs focalisants; - des méthodes de mesurage pour l'obtention de caractéristiques définies de transducteurs focalisants; - des méthodes d'alignement de l'axe du faisceau adaptées aux transducteurs focalisants. La présente Norme internationale se réfère à des transducteurs ultrasonores focalisants fonctionnant dans la plage de fréquences appropriée pour des applications ultrasonores médicales (soit de 0,5 MHz à 40 MHz) aussi bien thérapeutiques que diagnostiques. La présente norme montre comment les caractéristiques du champ transmis par les transducteurs peuvent être décrites du point de vue de la conception et mesurées par une personne n'ayant aucune connaissance préalable des détails de construction d'un appareil spécifique. Le champ ultrasonore émis pour une excitation spécifiée est mesuré par un hydrophone soit dans un milieu d'essai standard (par exemple de l'eau), soit dans un autre milieu donné. La Norme s'applique uniquement à des milieux où le comportement du champ est essentiellement similaire à celui constaté dans un fluide (c'est-à-dire où l'influence des ondes de cisaillement et de l'anisotropie élastique est faible), cela comprenant les tissus mous et les gels imitant un tissu. Tous les aspects du champ affectant leur description théorique ou qui sont importants pour la conception sont aussi inclus. Ces définitions peuvent être utiles dans des communications scientifiques, pour la conception d'appareils et pour la description du rendement et de la sécurité de systèmes utilisant ces dispositifs.

IEC 60565-1:2020(Main)
Underwater acoustics - Hydrophones - Calibration of hydrophones - Part 1: Procedures for free-field calibration of hydrophones

IEC 60565-1:2020 specifies methods and procedures for free-field calibration of hydrophones, as well as individual electroacoustic transducers that can be used as hydrophones (receivers) and/or projectors (source transducers). Two general types of calibration are covered within this document: absolute calibration using the method of three-transducer spherical-wave reciprocity, and relative calibration by comparison with a reference device which has already been the subject of an absolute calibration.
The maximum frequency range of the methods specified in this document is from 200 Hz to 1 MHz. The lowest acoustic frequency of application will depend on a number of factors, and will typically be in the range 200 Hz to 5 kHz depending mainly on the dimensions of the chosen test facility, The highest frequency of application for the methods described here is 1 MHz.
Procedures for pressure hydrophone calibration at low frequencies can be found in IEC 60565 2 [1] . Procedures for hydrophone calibration at acoustic frequencies greater than 1 MHz are covered by IEC 62127-2 [2].
Excluded from the scope of this document are low-frequency pressure calibrations of hydrophones, which are described in IEC 60565-2 [1]. Also excluded are calibrations of digital hydrophones and systems, calibration of marine autonomous acoustic recorders, calibration of acoustic vector sensors such as particle velocity sensors and pressure gradient hydrophones, calibration of passive sonar arrays consisting of multiple hydrophones, and calibration of active sonar arrays consisting of projectors and hydrophones.
This document presents a description of the requirements for free-field calibration in terms of test facility, equipment and instrumentation, signal processing, and frequency limitations. A description of achievable uncertainty and rules for the presentation of the calibration data are provided. Also included are informative annexes that provide additional guidance on
• measurement of directional response of a hydrophone or projector,
• measurement of electrical impedance of hydrophones and projectors,
• electrical loading corrections,
• acoustic far-field criteria in underwater acoustic calibration,
• pulsed techniques in free-field calibrations,
• assessment of uncertainty in the free-field calibration of hydrophones and projectors,
• derivation of the formulae for three-transducer spherical-wave reciprocity calibrations,
• calibration using travelling-wave tubes,
• calibration of hydrophones using optical interferometry, and
• calibrations in reverberant water tanks using continuous signals.
IEC 60565-1:2020 together with IEC 60565-2:2019, cancels and replaces the second edition of IEC 60565 published in 2006. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
1) removal of all descriptions of methods for pressure calibrations of hydrophones – these are now included in Part 2;
2) removal of the derivations of formulae for free-field reciprocity calibration (both amplitude sensitivity and phase sensitivity) and placement of these into an informative annex;
3) inclusion within the scope of the calibration of the transmitting response of individual source transducers and hydrophones (but not sonar arrays);
4) re-ordering of the sections within the document such that the more general procedures for calibration such as guidance on obtaining conditions of acoustic free-field, far-field, and steady-state, appear before the descriptions of procedures for absolute or relative calibrations;
5) revision of informative Annex A to include guidance on measurement of directional response of a hydrophone or projector;
6) addition of a new informative Annex B on measurement of electrical impedance of hydrophones and projectors;
7) revision of the previous informative annex on electrical loading corrections to include corrections to account for e
