Ultrasonics - Field characterization - Test methods for the determination of thermal and mechanical indices related to medical diagnostic ultrasonic fields
IEC 62359:2010 is applicable to medical diagnostic ultrasound fields. It establishes: - parameters related to thermal and non-thermal exposure aspects of diagnostic ultrasonic fields; - methods for the determination of an exposure parameter relating to temperature rise in theoretical tissue-equivalent models, resulting from absorption of ultrasound; - methods for the determination of an exposure parameter appropriate to certain non-thermal effects. This second edition cancels and replaces the first edition, published in 2005. It constitutes a technical revision. Major changes with respect to the previous edition include the following: - The methods of determination set out in the first edition of this standard were based on those contained in the American standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment (ODS) and were intended to yield identical results. While this second edition also follows the ODS in principal and uses the same basic formulae and assumptions (see Annex A), it contains a few significant modifications which deviate from the ODS. - One of the primary issues dealt with in preparing this second edition of IEC 62359 was 'missing' TI equations. In Edition 1 there were not enough equations to make complete 'at-surface' and 'below-surface' summations for TIS and TIB in combined-operating modes. Thus major changes with respect to the previous edition are related to the introduction of new calculations of thermal indices to take into account both 'at-surface' and 'below-surface' thermal effects.

Ultrasons – Caractérisation du champ – Méthodes d'essai pour la détermination d'indices thermique et mécanique des champs d'ultrasons utilisés pour le diagnostic médical
La CEI 62359:2010 est applicable aux champs d'ultrasons utilisés pour le diagnostic médical. Elle définit: - des paramètres relatifs aux aspects thermiques et non thermiques des champs ultrasonores de diagnostic; - des méthodes de détermination d'un paramètre d'exposition relatif à l'échauffement dans les modèles théoriques équivalents aux tissus, résultant de l'absorption d'ultrasons; - des méthodes de détermination d'un paramètre d'exposition approprié pour certains effets non thermiques. Cette deuxième édition annule et remplace la première édition publiée en 2005. Elle constitue une révision technique. Les modifications majeures par rapport à l'édition précédente incluent ce qui suit: - Les méthodes de détermination présentées dans la première de la présente norme étaient basées sur celles contenues dans la Norme américaine relative à l'affichage en temps réel des Indices d'émission acoustiques thermique et mécanique des appareils de diagnostics à ultrasons (ODS) et devaient fournir des résultats identiques. Bien que l'édition seconde suive également l'ODS dans le principe et utilise les mêmes formules et hypothèses fondamentales (voir Annexe A), elle comporte quelques modifications significatives s'écartant de l'ODS. - L'une des principales questions traitées lors de l'élaboration de l'édition seconde de la CEI 62359 norme faisait référence aux équations de TI 'manquantes'. Elles n'étaient pas suffisantes dans l'édition 1 afin d'effectuer des sommations 'à la surface' et 'sous la surface' complètes pour TIS et TIB en modes de fonctionnement combinés. Ainsi, les modifications majeures par rapport à l'édition précédente sont liées à l'introduction de nouveaux calculs d'indices thermiques pour prendre en compte les effets thermiques 'à la surface' et 'sous la surface'.

Foreword
The text of document 87/445/FDIS, future edition 2 of IEC 62359, prepared by IEC TC 87, Ultrasonics,
was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62359 on
2011-02-01.
This European Standard supersedes EN 62359:2005.
Major changes with respect to EN 62359:2005 include the following:
– The methods of determination set out in EN 62359:2005 were based on those contained in the
American standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices on
Diagnostic Ultrasound Equipment (ODS) and were intended to yield identical results. While
EN 62359:2010 also follows the ODS in principal and uses the same basic formulae and assumptions
(see Annex A), it contains a few significant modifications which deviate from the ODS.
– One of the primary issues dealt with in preparing EN 62359:2010 was “missing” TI equations. In
EN 62359:2005 there were not enough equations to make complete “at-surface” and “below-surface”
summations for TIS and TIB in combined-operating modes. Thus major changes with respect to
EN 62359:2005 are related to the introduction of new calculations of thermal indices to take into account
both "at-surface" and "below-surface" thermal effects.
